TPS3840DL29DBVR Product Details

Wide Vin allows monitoring 9V rails or batteries without external components and 24Vrails with external resistors. Nano-Iq extends battery life for low power applications andminimizes current consumption when using external resistors. Fast start-up delay allows thedetection of a voltage fault before the rest of the system powers up providing maximum safety inhazardous start-up fault conditions. Low Power-on-Reset (VPOR) preventsfalse resets, premature enable or turn-on of next device, and proper transistor control duringpower-up and power-down.

Reset output signal is asserted when the voltage at VDD dropsbelow the negative voltage threshold (VIT-) or when manual reset(MR) is pulled to a low logic(VMR_L). Reset signal is cleared whenVDD rise above VIT- plus hysteresis(VIT+) and manual reset is floating or aboveVMR_H and the reset time delay(tD) expires. Reset time delay can be programmed by connecting a capacitorbetween CT pin and ground. For a fast reset CT pin can be left floating.

Additional features: Built-in glitch immunity protection for MRand VDD, built-in hysteresis, low open-drain output leakage current(ILKG(OD)).
