LF2136B 3-Phase Half Bridge Gate Driver Integrated Circuits IC LF2136BTR(Electronic Components )

Description :

LF2136B is a three-phase gate driver IC designed for high voltage, high speed applications, driving N-channel
MOSFETs and IGBTs in a half-bridge configuration.

The high voltage process enables the LF2136B high sides to switch up to 600V in a bootstrap operation.
LF2136B logic inputs are compatible with standard TTL and CMOS levels (down to 3.3V) to interface easily with controlling devices and are enabled low to better function in high noise environments. The driver outputs feature high pulse current buffers designed for minimum driver cross conduction.
LF2136B offers numerous protection functions. A shoot-through protection logic prevents both outputs being high with both inputs low (fault state), an under-voltage lockout (UVLO) for VCC shuts down all drivers through an internal fault control, while a UVLO for VBS shuts down the respective high side output.
Additionally an overcurrent protection will terminate all six outputs. Both the VCC UVLO and the overcurrent protection activate an automatic fault clear with a timing that is adjustable with an external capacitor.
LF2136B is offered in an SOIC-28 package and operates over an extended temperature range of -40 °C to +125 °C .
