PIN CONNECTIONS (top view)

TD310 includes a current sense comparator which inhibit the output drivers in case of overcurrent. An alarm output signals the even to a controller.

TD310 also includes an uncommitted op-amp which can be u sed for current measurement (as an amplifier before the A/D input of a microcontroller) of for other general purpose.

Programmable undervo ltage lockout and standby mode make TD310 suitable for a large area of environment and application.

Typical applications are low side IG BT and power MOSFET drive in three phase systems, pulse transformer drive, and general purpose pulse drive.
