Versatile 36V window comparator / dual independent monitor

21-01-2015 | Mouser Electronics | Semiconductors

Mouser now stocks the Texas Instruments (TI) 36V TPS3701, a wide supply voltage window comparator that operates over a 1.8V to 36V range. The device has two precision comparators with an internal 400mV reference and two open-drain outputs (OUTA and OUTB) rated to 25V for over- and under-voltage detection. It can be used as a window comparator or as two independent voltage monitors. The monitored voltage is set with the use of external resistors. OUTA is driven low when the voltage at the INA pin drops below the negative threshold, and goes high when the voltage returns above the positive threshold. OUTB is driven low when the voltage at the INB pin rises above the positive threshold, and goes high when the voltage drops below the negative threshold. Both comparators in the TPS3701 include built-in hysteresis for noise rejection, thereby ensuring stable output operation without false triggering. Typical applications include industrial control systems, embedded computing modules, DSPs, microcontrollers, microprocessors, notebook / desktop computers, portable and battery-powered products, and FPGA / ASIC systems.
