TPS3820-33DBVR TI Supervisors

The TPS3820-33DBVR is a microprocessor supervisory circuit from Texas Instruments in 5-pin SOT-23 (DBV) package, monitoring 3.3V supply threshold with active-low reset output. For selection, verify reset threshold of 2.93V (for 3.3V monitoring), reset timeout of 200ms typical, watchdog timer with 200ms timeout, supply current of 15µA typical, manual reset input, push-pull reset output, and operating temperature from -40°C to +85°C. Features include watchdog timer for software execution monitoring, manual reset input for external override, guaranteed reset valid down to VCC=1.1V, and excellent transient immunity. Ideal for 3.3V microprocessor and microcontroller systems requiring power-on reset, brown-out protection, and software execution monitoring via watchdog timer in industrial controllers, automotive electronics, and embedded systems.
