3 Description

The TPS3760-Q1 is a 65 V input voltage detector with

1 μA IDD and 1 accuracy, and a fast detection time.

This device can be connected directly to 12 V / 24 V

automotive battery system for continuous monitoring

of over (OV) or under (UV) voltage conditions; with

its internal resistor divider, it offers the smallest total

solution size. Wide hysteresis voltage options are

available to ignore cold crank, start-stop and various

car battery voltage transients. Built-in hysteresis on

the SENSE pin prevents false reset signals when

monitoring a supply voltage rail.

The separate VDD and SENSE pins allow

redundancy sought by high-reliability automotive

systems and SENSE can monitor higher and lower

voltages than VDD. Optional use of external resistors

are supported by the high impedance input of

the SENSE pin. CTS and CTR pins allow delay

adjustability on the rising and falling edges of the

RESET signals. Also, CTS functions as a debouncer

by ignoring voltage glitches on the monitored voltage

rails; CTR operates as a manual reset (MR) that can

be used to force a system reset.

The TPS3760 is available in a 4.1-mm×1.9-mm SOT

14-pin package. TPS3760 operates over –40°C to

+125°C TA.
