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

The TPL5110 Power Timer is a stand-alone breakout that will turn any electronics into low-power electronics! It will take care of turning your project on/off using a built in timer that can vary from once-every 100ms up to once every two hours. Basically, the TPL will turn on periodically, adjustable by potentiometer or resistor, and turn on your project's power. It will then wait until a signal is received from the project to tell the TPL that it can safely turn off the power. If the TPL does not receive a signal by the set time-out, it will reset the device like a watchdog timer. #Sublayout #Module #PowerTimer #TPL5110
