Description
The TF23892 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.
Telefunken’s high voltage process enables the TF23892
high sides to switch to 600V in a bootstrap operation.
The TF23892 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.
The TF23892 offers numerous protection functions. A
shoot-through protection logic prevents both outputs
being high with both inputs high (fault state), an

respective high side output. Also an overcurrent protection
will terminate the six outputs.

The TF23892 is offered in SOIC 28 package and operates
over an extended -40 °C to +125 °C temperature range.
