Fast UV/OV protection in 12/24/48V systems
The TPS3762-Q1 is a 65V input voltage supervisor with 4μA IDD, 0.9% accuracy, fast detection time (5μs), and a Built-In Self-Test feature. This device can be connected directly to 12V / 24V automotive battery systems for continuous monitoring of overvoltage (OV) and undervoltage (UV) conditions; with the internal resistor divider, the TPS3762-Q1 offers the smallest total solution size. Wide hysteresis voltage options are available to ignore large voltage transients and prevent false reset signals.
The separate VDD and SENSE pins allow redundancy sought by high-reliability 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 falling and rising edges of the RESET signal. The CTS functions as a debouncer by ignoring voltage glitches on the monitored voltage rails.
The TPS3762-Q1 is available in a 2.9mm × 1.6mm SOT23 8-pin package.
Device Decoder in Section 5 describe how to decode certain device function of the device based on its part number. Not all part numbers follow this nomenclature. Use Table 4-1 as the part number decoding table for all devices.
