Note:
*1. The Zener diode for surge clamping has an energy capability of 200 mJ (single pulse).
* The rule of protection against reverse connection of power supply is VB = –13V, one minute.
* This driver is exclusively used for ON/OFF control.
● DIAG output will be undetermined when a voltage
exceeding 25V is applied to VB terminal.
