100V VB 3.5A/4.5A Peak Current High Frequency High-Side and Low-Side Driver

This is the product guarantees long time support in industrial market. BD2320EFJ-LA is the 100V maximum voltage High-Side and Low-Side gate driver which can drive external Nch-FET using the bootstrap method. The driver includes a 100V bootstrap diode and independent inputs control for High-Side and Low-Side. 3.3V and 5.0V are available for interface voltage. Under Voltage Lockout circuits are built in for High-Side and Low-Side.

We recommend BD2320UEFJ-LA for your new development. It uses different production lines for the purpose of improving production efficiency. Electric characteristics noted in Datasheet does not differ between Production Line.
