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. If you're looking for high-quality timers and RTCs for your electronic projects, you should check out Flux.ai.

105 Uses0 StarsTPS3828-33DBVR
Supervisor Open Drain or Open Collector 1 Channel SOT-23-5 The TPS382x family of supervisors provide circuit initialization and timing supervision, primarily for DSP and processor-based systems. During power on, RESET asserts when the supply voltage VDD becomes greater than 1.1V. Thereafter, the supply voltage supervisor monitors VDD and keeps RESET active low as long as VDD remains less than the threshold voltage, VIT−. An internal timer delays the return of the output to the inactive state (high) to make sure proper system reset. The delay time, td, starts after VDD has risen above the threshold voltage (VIT− + VHYS). When the supply voltage drops below the threshold voltage VIT−, the output becomes active (low) again. No external components are required. All the devices of this family have a fixed-sense threshold voltage, VIT–, set by an internal voltage divider. The TPS382x family also offers watchdog time out options of 200ms (TPS3820) and 1.6s (TPS3823, TPS3824, and TPS3828). • Power-on reset generator with a fixed delay time of 200ms (TPS3823, TPS3824, TPS3825, and TPS3828) or 25ms (TPS3820) • Manual reset input (TPS3820, TPS3823, TPS3825, and TPS3828) • Reset output available in active-low (TPS3820, TPS3823, TPS3824, and TPS3825), active-high (TPS3824 and TPS3825), and open drain (TPS3828) • Supply voltage supervision range: 2.5V, 3V, 3.3V, 5V • Watchdog timer (TPS3820, TPS3823, TPS3824, and TPS3828) • Supply current of 15μA (typical) • 5-pin SOT-23 package • Temperature range: −40°C to 85°C (−40°C to 125°C for TPS3823A-33) #CommonPartsLibrary #IntegratedCircuit #PowerManagement #Supervisor

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
