EVAL6393FB Datasheet, PDF (1/9 Pages) STMicroelectronics – Carefully optimized layout

EVAL6393FB
Low voltage full-bridge demonstration board based on the L6393
advanced high voltage gate driver
Data brief
Features
■ ~150 W drive capability (50 V - 3.0 A_r.m.s.)
■ Very low area occupation, all devices and
power switches in SMD package (no heatsink)
■ Fast-decay or slow-decay on-board constant
off-time peak current control
■ PWM voltage mode control with overcurrent
protection possible via external logic signals
■ Driver supply voltage on-board generation
directly from BUS voltage
■ Carefully optimized layout
Description
The EVAL6393FB demonstrates how to use two
L6393 drivers to drive a single-phase load
through a full-bridge topology. This allows both
the direction and the value of the current flowing
into the load to be controlled. Typical loads, which
can be effectively driven by using this topology,
are single-phase BLDC motors, fans and HID
lamps. Thanks to the integrated features of the
L6393, the board has a very small footprint and
an optimized layout, and can be simply run by
applying the BUS voltage and a direction signal.
