40 V adjustable voltage supervisor

23 November 2022 Power Electronics / Power Management

The TL7700-SEP from Texas Instruments is a bipolar integrated circuit designed for use as a reset controller in microcomputer and microprocessor systems. The SENSE voltage can be set to any value greater than 0,5 V using two external resistors. Reset threshold accuracy is 2%.

Circuit function is very stable, with a wide supply voltage in the 1,8 to 40 V range. Minimum supply current of only 0,6 mA allows use with AC line operation and portable battery operation.

The time delay on the device is programmable. The TL7700-SEP device is designed for operation from –55 to 125°C.
