Description

Wide Vin allows monitoring 9V rails or batteries without external components and 24V rails with external resistors. Nano-Iq extends battery life for low power applications and minimizes current consumption when using external resistors. Fast start-up delay allows the detection of a voltage fault before the rest of the system powers up providing maximum safety in hazardous start-up fault conditions. Low Power-on-Reset (VPOR) prevents false resets, premature enable or turn-on of next device, and proper transistor control during power-up and power-down. Reset output signal is asserted when the voltage at VDDdrops below the negative voltage threshold (VIT-) or when manual reset (MR) is pulled to a low logic (VMR_L). Reset signal is cleared when VDDrise above VIT-plus hysteresis (VIT+) and manual reset is floating or above VMR_Hand the reset time delay (tD) expires. Reset time delay can be programmed by connecting a capacitor between CT pin and ground. For a fast reset CT pin can be left floating. Additional features: Built-in glitch immunity protection forMRand VDD, built-in hysteresis, low open-drain output leakage current (ILKG(OD)).
