Application
•
Dedicated for DC-brush high current motor bridges in PWM control mode and adapted for use in injector and
valve applications for 12, 24 and 42V powernet applications. Useable as four fold lowside driver for unipolar 4
phase motor drives.
•
The two half bridges can operate independently. The two half bridges can even operate at different supply
voltages.
General Description
Dual half bridge driver IC for MOSFET power stages with multiple protection functions.

This application diagram shows the principle schematics of a typical injector / valve drive. Other
configurations are possible as well. Freewheeling diodes are not considered. The 10 m resistor
is not needed by the Driver IC, but may be needed for load current measurement. The voltage
devider networks, e.g. R = 10 k, across the two Low Side MOSFETs are an example as well;
they allow to increas the current limit threshold for Short Circuit protection SCD for the Low Side
MOSFETs. As they pull down the Sources of the High Side MOSFETs (while the Low Side MOSFETs are off), they allow to pre-charge the C
capacitors during start-up (before the Driver IC
Bx
gets enabled). The SCD current limit threshold can be increased for the High Side MOSFETs as
well by using voltage devider networks across the High Side MOSFETs. SCD can also be disabled (High Side and / or Low Side MOSFETs).
