TPS3840/TPS3840-Q1 Nanopower Voltage Supervisors

Texas Instruments TPS3840/TPS3840-Q1 Nanopower High-Input Voltage Supervisors come with a wide Vin, which 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 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 the next device, and proper transistor control during power-up and power-down.
