3 Description

The TPS3760 is a family of wide input range and

low quiescent current window supervisors for fast

detection of overvoltage (OV) or undervoltage (UV)

conditions. The TPS3760 can be connected directly

to and monitor 12 V / 24 V supply rails in a variety

of industrial applications including factory automation,

motor drives, building automation and others. Built-in

hysteresis on the SENSE pins prevents false reset

signals when monitoring a supply voltage rail.

The separate VDD and SENSE pins allow

redundancy sought by high-reliability systems.

SENSE is decoupled from VDD and can monitor

higher and lower voltages than VDD. Optional use

of external resistors are supported by the high

impedance input of the SENSE pins. CTSx and CTRx

pins allow delay adjustability on the rising and falling

edges of the RESET signals. Also, CTSx functions

as a debouncer by ignoring voltage glitches on the

monitored voltage rails; CTRx 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.
