Texas Instruments TPS3762/TPS3762-Q1 65V Window Supervisors have 4µA IDD, 0.9% accuracy, fast detection time, and a built-in self-test feature. These devices can be connected directly to 12V/24V industrial SELV power rails for continuous monitoring of overvoltage (OV) and undervoltage (UV) conditions; with its internal resistor divider, TPS3762/TPS3762-Q1 offers a small total solution size. Wide hysteresis voltage options are available to ignore large voltage transients. A 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 systems, and SENSE can monitor higher and lower voltages than VDD. The high impedance input of the SENSE pin supports the optional use of external resistors. CTR and CTS pins allow delay adjustability on the falling and rising edges of the RESET signal. The CTS functions as a debouncer by ignoring voltage glitches on the monitored voltage rails.
The Texas Instruments TPS3762/TPS3762-Q1 is available in a 2.9mm×1.6mm SOT-23 8-pin package and operates over -40°C to +150°C TA. The Texas Instruments TPS3762-Q1 devices are AEC-Q100 qualified for automotive applications.
