TPS3840DL17DBVR Integrated Circuit Chip High Input Voltage Supervisor With MR And Programmable Delay

Product Description Of TPS3840DL17DBVR
TPS3840DL17DBVR 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.
