Multichannel window supervisor with high accuracy and compact form factor

The TPS3704x is a low-power precision window

or standard voltage supervisor that can be configured as a quad, triple, or dual channel.

Each channel has a threshold accuracy of ±1% in an 8-pin (1.6

mm x 2.9 mm) SOT-23 package offering a small solution size. The TPS3704x includes a very

accurate threshold detection, with high resolution, that is ideal for systems that operate

on low-voltage supply rails and have narrow margin supply tolerances. Built-in low threshold

hysteresis and a fixed reset delay prevent false reset signals when monitoring multiple

voltage rails.

The TPS3704x does not require any external

resistors for setting the over and undervoltage reset thresholds, which further optimizes

overall high accuracy, cost, solution size, and improves reliability for safety systems.

Separate VDD and SENSEx pins allow

monitoring of rail voltages other than VDD or can be used as a push-button input. Optional

use of external resistors are supported by the SENSEx pins. Each channel on the TPS3704x can

be customized to its own over and undervoltage window detection with an upper and lower

threshold tolerance that can be symmetric or asymmetric.
