Switches
A switch is a device that allows electricity to flow through a circuit by completing or interrupting the connection. It is a common component in electrical and electronic systems and is used in a variety of applications, such as controlling the flow of electricity in a circuit, turning devices on and off, and routing electrical signals. One of the primary use cases for switches is to control the flow of electricity in a circuit. This can be done by manually flipping the switch or by using a control mechanism, such as a timer or a sensor. Another common use for switches is to turn devices on and off. This can be done using a switch that is built into the device or by using a separate switch that is connected to the device. In addition to these basic use cases, switches can also be used to route electrical signals. For example, a switch can be used to route a signal from one device to another or to direct a signal to a specific circuit or component.

TPS48100QDGXRQ1
High-Side Gate Driver IC Non-Inverting 19-VSSOP The TPS48100QDGXRQ1 is an automotive-grade dual high-side gate driver integrated circuit manufactured by Texas Instruments. It is designed to drive external N-channel power MOSFETs configured as high-side switches, providing the gate-drive voltage and current needed to turn the switches fully on and off with controlled timing. The device targets automotive and other harsh-environment power switching applications where a robust, low quiescent current solution is needed to control loads such as motors, relays, solenoids, lighting, and other inductive or resistive loads powered from a vehicle battery rail. As a member of TI's automotive low-IQ high-side driver portfolio, the device is built to tolerate the wide voltage swings and transient conditions characteristic of automotive electrical systems, including load dump events and cold-crank voltage sags, while maintaining very low standby current draw when the driven loads are not active. This low quiescent current characteristic is particularly valuable in always-on automotive modules, where minimizing parasitic battery drain during vehicle-off states is a key design requirement. The device's two independent driver channels operate synchronously, allowing coordinated control of dual high-side switches from a shared set of control and protection circuitry, which is useful in applications such as dual-channel load switching, H-bridge-adjacent driver stages, or redundant power path control. The non-inverting input structure means that the gate driver outputs follow the logic state of the input control signals directly, simplifying integration with microcontroller-based control logic without requiring additional inverting stages. Internally, the device manages the charge pump or bootstrap circuitry needed to generate a gate voltage above the battery rail, which is necessary to fully enhance an N-channel MOSFET configured in the high-side position. This internal voltage generation simplifies the external bill of materials compared to discrete charge-pump driver implementations. The device is qualified to automotive electronics reliability standards, reflecting the rigorous stress testing and quality requirements expected of components used in vehicle electrical and powertrain-adjacent systems. It is housed in a small-outline surface-mount package suited to space-constrained automotive control module designs, and it is supplied in tape-and-reel or cut-tape packaging formats to support both high-volume automated assembly and lower-volume prototyping needs.

N-Channel 30 V 161A (Tc) 140W (Tc) Surface Mount TO-252AA (DPAK) The IRLR7843TRPBF is an N-channel power MOSFET built on Infineon's HEXFET technology platform, originally developed by International Rectifier. It is designed as a low-voltage, high-current switching device intended for applications where minimizing conduction loss and maximizing efficiency are primary design goals. The part is particularly well suited to synchronous switching topologies, where pairs or arrays of MOSFETs alternately conduct to regulate power flow with minimal energy dissipation. This device targets high-density power conversion applications where board space is limited but current demands are substantial, such as notebook computer power delivery, point-of-load converters used in servers, and advanced telecom and datacom equipment. It is commonly found supporting synchronous buck converter stages that step down a higher input rail to a lower output voltage suitable for powering processors, memory, and other low-voltage digital logic. Its low on-resistance characteristic allows it to carry significant current while generating comparatively little resistive heating, which is essential in compact enclosures with constrained thermal budgets. The transistor is fabricated using a refined trench gate process that improves upon earlier HEXFET generations, offering reduced gate charge and lower switching losses alongside its low conduction resistance. This combination makes it effective in both the high-side and low-side positions of a synchronous switching cell, where fast, clean transitions reduce overlap losses and improve overall converter efficiency. The device also offers well-characterized avalanche energy ratings, giving designers confidence in its ruggedness when exposed to transient overvoltage events that can occur during switching, and it presents a very low gate impedance, allowing it to be driven efficiently by standard gate driver circuitry. Mechanically, the part is housed in a surface-mount power package with an exposed tab for enhanced thermal conduction to the host PCB, allowing heat generated during operation to be efficiently transferred away from the silicon die. This package style is widely used in power-dense designs where through-hole packages would be impractical. The device is supplied in a tape-and-reel format suitable for automated assembly and is compliant with RoHS material restrictions, reflecting current environmental and regulatory standards for electronic components.
