Product Overview
TPS3838 is a Texas Instruments nano power voltage supervisor in the Power_Management category. It is specified for a recommended supply voltage range of 1.6 V to 6 V, with an absolute maximum supply voltage rating of 7 V. The operating free-air temperature range is -40°C to 85°C, and the storage temperature range is -65°C to 150°C.
Package options include a 5-pin SOT23/SOT (DBV) with a 2.90 mm × 1.60 mm body and a 6-pin WSON/SON (DRV) with a 2.00 mm × 2.00 mm body. Reset timing is set through the CT connection, with 10 ms typical delay when CT is connected to GND and 200 ms typical delay when CT is connected to VDD.
Electrical parameters include supply current of 220 nA typical for VDD above threshold and below 3 V, 250 nA typical for VDD above threshold and above 3 V, and 10 µA typical when VDD is below threshold. The device supports manual reset circuitry, threshold hysteresis values from 30 mV to 50 mV typical, and ESD ratings of 4000 V HBM and 1000 V CDM.
