Introduction
TPS37 is a family of wide input range, low quiescent current window monitors designed 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 directly connected to and monitor 12V/24V power rails in various industrial applications, including factory automation, motor drives, building automation, and more. Built-in hysteresis on the SENSE pin prevents false reset signals when monitoring power supply voltage rails.
Separate VDD and SENSE pins provide the redundancy required for high-reliability systems. SENSE is decoupled from VDD and can monitor voltages both above and below VDD. The high-impedance input of the SENSE pin supports the use of optional external resistors. The CTSx and CTRx pins allow delay adjustment of the rising and falling edges of the RESET signal. In addition, CTSx can ignore voltage glitches on the monitored voltage rail, functioning as a debouncer; CTRx serves as a manual reset (MR) function and can be used to force a system reset.
The TPS37 is available in WSON or SOT-23 packages. Per the guidelines in IEC60664, the center pad is non-conductive to increase the creepage distance between VDD and GND. The TPS37 operates over a temperature range of –40°C to +125°C TA.
Features
- Wide supply voltage range: 2.7V to 65V
- SENSE and RESET pins rated at 65V
- Low quiescent current: 1μA (typical)
- Flexible and wide voltage threshold options
- Built-in hysteresis (VHYS) percentage options: 2% to 13% (1% step); fixed options: VTH<8V = 0.5V, 1.5V, 2V, 2.5V
- Programmable reset delay time: 10nF = 12.8ms, 10μF = 12.8s
- Programmable detection delay time: 10nF = 1.28ms, 10μF = 1.28s
- Manual reset (MR) function
- Output reset latch function
- Output topology: open-drain or push-pull
Applications
- Analog input module CPU (PLC controller)
- Servo driver control module
- Servo driver power stage module
- Servo driver functional safety module
- HVAC valve and actuator control
