TPS3421ECDRYR Description

Short technical summary and product information.

The TPS3421ECDRYR from Texas Instruments is a low-power, ultrasmall dual-channel push-button controller designed for system reset functions. It monitors two supply voltages and provides a configurable delay for system resets, avoiding unintended resets from glitches.

 

Key electrical specifications include a low quiescent current of 250 nA typical, an operating voltage range of 1.6 V to 6.5 V, and an active-low, open-drain output. The device offers user-selectable input delay options, such as 7.5 s and 0 s, and a fixed time-out pulse at RST of 400 ms typical. The reset timeout is a minimum of 64ms.

 

This supervisor IC is housed in a very small 6-SON package measuring 1.45 mm x 1 mm, making it suitable for space-constrained applications. It is designed for surface mount installation. The operating temperature range is -40°C to 125°C (TJ).
