High Current PN Half Bridge

About this document

Scope and purpose

This Application Note is intended to provide information and hints for a high current design, using PWM control

with the NovalithIC™ half-bridge family BTN89xy for the automotive environment.

Note:

The following information is only given to help with the implementation of the device and shall not be

regarded as a description or warranty of a certain functionality, condition or quality of the device.

Abstract

This family contains one P-channel high-side MOSFET and one N-channel low-side MOSFET with an integrated

driver IC in one package. The NovalithIC™ BTN89xy is the interface between the microcontroller and the motor,

equipped with diagnostic and protection functions.

Block Diagram BTN89xy

As both the high-side and low side switch are placed on one single leadframe this results in many system

benefits: Resulting from the low distance between the high-side MOSFET and the low-side MOSFETthe stray

inductance between them is minimal thus minimizing negative voltage spikes at OUT during switching and

improving EMC. As the voltage level of the leadframe is on the output of the half-bridge, only one single cooling

area is required (on OUT potential) for the device, thus being used for both a high-side or low-side current

switching. For a state of the art N-channel solution, usually two cooling areas are required, each for the high-

side and low-side MOSFET.
