ZHCS840G February 2012 – February 2019 TPS3700
The TPS3700 device combines two voltage detectors for overvoltage and undervoltage detection. The TPS3700 device is a wide-supply voltage range (1.8 V to 18 V) device with a high-accuracy rising input threshold of 400 mV (1% over temperature) and built-in hysteresis. The outputs are also rated to 18 V and can sink up to 40 mA.
The TPS3700 device is designed to assert the output signals, as shown in Table 1. Each input terminal can be set to monitor any voltage above 0.4 V using an external resistor divider network. With the use of two input terminals of different polarities, the TPS3700 device forms a window voltage detector. Broad voltage thresholds can be supported that allow the device to be used in a wide array of applications.
|INA+ > VIT+||OUTA high||Output A not asserted|
|INA+ < VIT–||OUTA low||Output A asserted|
|INB– > VIT+||OUTB low||Output B asserted|
|INB– < VIT–||OUTB high||Output B not asserted|
