TPS3801-01DCKR Description

Short technical summary and product information.

The Texas Instruments TPS3801-01DCKR is an ultra-small supply voltage supervisor designed for circuit initialization and timing supervision, particularly for processor-based systems. It provides a power-on reset generator with a fixed delay time of 200 ms.

 

This device monitors a single supply voltage and asserts a push-pull RESET signal when the voltage drops below a preset threshold. The RESET output remains asserted for the programmed delay time after the voltage returns above the threshold. The TPS3801-01DCKR features manual reset capability and a reset threshold accuracy of 2% typical.

 

It operates over a temperature range of -40°C to +85°C and consumes a low supply current of 9 µA typical. The supervisor is available in a compact 5-pin SC-70 (SOT-323) package, making it suitable for space-constrained applications.

 

Applications include systems using DSPs, microcontrollers, or microprocessors, wireless communication systems, portable/battery-powered equipment, and industrial equipment.
