TPV821 Datasheet | 3PEAK

Features - Precision low voltage monitoring - 200 ms (typical) reset timeout - Manual reset input - Reset output stage - Open Drain Active-low output (TPV821) - Low power consumption: 2.2 μA - Guaranteed reset output valid to VCC = 1 V - Power supply glitch immunity - Specified from - 40°C to +125°C - 5-lead SOT-23-5 package and 4-lead SOT-143 package Applications - Microprocessor systems - puters - Controllers - Intelligent instruments - Portable equipment Description The TPV821 is a supervisory circuit that monitors power supply voltage levels and provides a power-on reset signal. A reset signal can also be asserted by an external manual reset input. The reset periods are fixed at 200 ms (typical). The TPV821 is available in a 5-lead SOT-23-5 package and 4-lead SOT-143 package. And typically consumes only 2.2 μA, suitable for use in low power, portable applications.
