The TPS37 is a family of wide input range and low quiescent current window supervisors for fast detection of overvoltage (OV) and undervoltage (UV) conditions. Each device includes a precision internal reference, two independent and configurable voltage comparators and integrated resistor dividers. The TPS37 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.
TPS37 is available in a WSON or SOT-23 package. The central pad is non-conductive to increase the creepage between VDD and GND per guidelines in IEC60664. TPS37 operates over –40°C to +125°C T A.
