TPS3701 features: open-drain output for overvoltage and undervoltage detection; high threshold accuracy; 0.75% overtemperature; internal hysteresis: 5.5mV (typical)
TPS3701 Typical Applications: Industrial Control Systems; Embedded Computing Modules; Notebooks and Desktops; Portable and Battery-Powered Products
TPS3701 reference design application circuit:
Figure 1 TPS3701 internal structure diagram
The TPS3701 combines two comparators with a precision reference voltage. Each comparator has one external input; the other input is connected to the internal reference. The rising threshold on INB and the falling threshold on INA are designed and trimmed to be equal to the reference voltage (400 mV).
Figure 2 TPS3701 reference design
The TPS3701 wide-supply voltage window comparator operates over a 1.8-V to 36-V range. The device has two precision comparators with an internal 400-mV reference and two open-drain outputs (OUTA and OUTB) rated to 25 V for over - and undervoltage detection.
