Timers and RTCs
Timers and Real-Time Clocks (RTCs) are electronic devices that are used to measure time or keep track of the current time. They can be found in a wide range of applications, including computers, phones, and appliances. Timers are used to trigger an action after a specific period of time has elapsed. They can be used to control the duration of an event, or to schedule tasks to be performed at a later time. RTCs, on the other hand, are used to maintain accurate time even when the device is powered off. They are often used in devices that need to keep track of the current time and date, such as alarm clocks and smart thermostats.

NE555P
555 Type, Timer/Oscillator (Single) IC 100kHz 8-PDIP NE555 DIP-8 through hole The NE555P is a classic and widely used precision timer IC manufactured by companies like Texas Instruments and others. It belongs to the popular 555 timer family and is designed for generating accurate time delays, oscillations, and pulse signals. The “P” variant refers to the PDIP (Plastic Dual In-line Package), making it ideal for through-hole mounting, breadboarding, and prototyping. NE555P PDIP-8 timer Internally, the NE555P consists of: Two comparators A flip-flop A discharge transistor A voltage divider network These blocks allow flexible configuration for timing and waveform generation.

555 Type, Timer/Oscillator (Single) IC 2.1MHz 8-PDIP The TLC555 is a CMOS monolithic timing circuit. The timer is fully compatible with CMOS, TTL, and MOS logic and operates at frequencies up to 2MHz. Because of a high input impedance, this device supports smaller timing capacitors than those supported by the NE555 or LM555. As a result, more accurate time delays and oscillations are possible. Power consumption is low across the full range of power-supply voltage. • Very low power consumption: – 1mW typical at VDD = 5V • Capable of operation in astable mode • CMOS output capable of swinging rail to rail • High output current capability – Sink: 100mA typical – Source: 10mA typical • Output fully compatible with CMOS, TTL, and MOS • Low supply current reduces spikes during output transitions • Single-supply operation from 2V to 15V • Functionally interchangeable with the NE555; has same pinout • ESD protection exceeds 1000V per ANSI/ESDA/ JEDEC JS-001 • Available in Q-temp automotive – High-reliability automotive applications – Configuration control and print support – Qualification to automotive standards #CommonPartsLibrary #IntegratedCircuit

IC SURGE STOPPER 2.7V~23V VQFN-10-HR(2x2) The TPS25947xx family of eFuses is a highly integrated circuit protection and power management solution in a small package. The devices provide multiple protection modes using very few external components and are a robust defense against overloads, short-circuits, voltage surges, reverse polarity and excessive inrush current. With integrated back-to-back FETs, reverse current flow from output to input is blocked at all times, making the devices an excellent choice for power MUX/ORing applications as well as systems which need load side energy hold up storage in case input power supply fails. The devices use linear ORing based scheme to establish an almost zero DC reverse current and emulate ideal diode behavior with minimum forward voltage drop and power dissipation. Output slew rate and inrush current can be adjusted using an external capacitor. Loads are protected from input overvoltage conditions either by clamping the output to a safe fixed maximum voltage (pin selectable), or by cutting off the output if input exceeds an adjustable overvoltage threshold. The devices respond to output overload by actively limiting the current or breaking the circuit. The output current limit threshold as well as the transient overcurrent blanking timer are user adjustable. The current limit control pin also functions as an analog load current monitor. The devices are available in a 2mm × 2mm, 10- pin HotRod™ QFN package for improved thermal performance and reduced system footprint. The devices are characterized for operation over a junction temperature range from –40°C to +125°C. • Wide operating input voltage range: 2.7V to 23V – 28V absolute maximum – Withstands negative voltages up to –15V • Integrated back-to-back FETs with low onresistance: RON = 28.3mΩ (typical) • Ideal diode operation with true reverse-current blocking • Fast overvoltage protection – Overvoltage clamp (OVC) with pin-selectable threshold (3.8V, 5.7V, 13.8V) and 5μs (typical) response time OR – Adjustable overvoltage lockout (OVLO) with 1.2μs (typical) response time • Overcurrent protection with load current monitor output (ILM) – Active current limit OR circuit-breaker options – Adjustable threshold (ILIM) 0.5A to 6A • ±10% accuracy for ILIM > 1A – Adjustable transient blanking timer (ITIMER) to allow peak currents up to 2 × ILIM – Output load current monitor accuracy: ±6% (IOUT ≥ 1A) • Fast-trip response for short-circuit protection – 500ns (typical) response time – Adjustable (2 × ILIM) and fixed thresholds • Active high enable input with adjustable undervoltage lockout threshold (UVLO) • Adjustable output slew rate control (dVdt) • Overtemperature protection • Digital outputs – Priority power MUX control (AUXOFF) and fault indication (FLT) or – Power Good indication (PG) with adjustable threshold (PGTH) • UL 2367 recognition – File No. E339631 – RILM ≥ 750Ω • IEC 62368-1 CB certified • Small footprint: QFN 2mm × 2mm, 0.45mm pitch #CommonPartsLibrary #IntegratedCircuit #PowerManagement
