Si823H7BD-AS3

Automotive Isolated Gate Drivers;

The Si823H7BD-AS3 automotive isolated gate driver offers very high transient immunity of 125 kV/µs, low propagation delays of 30 ns max for better timing margins, a symmetric drive strength of 4.0 A sink and source with a drive boost circuit allowing faster FET turn-on and stable operation over automotive temperatures of -40 to 125 °C. It offers critical safety features such as driver side UVLO options and over-temperature protection and compact size benefits. Isolation ratings of 2.5 kVrms are available. Si823H7BD-AS3 isolators are offered in a Dual Driver configuration.\n\n
