Description
Channel 1 LS driver output.
A little series resistor helps in reducing device-dissipated power.
LS drivers supply: it can be varied from 5V to 12V buses.
Filter locally with at least 1µF ceramic cap vs. PGND.
Channel 1 HS driver return path. It must be connected to the HS1 mosfet source
and provides the return path for the HS driver of channel 1.
Channel 1 HS driver output.
A little series resistor helps in reducing device-dissipated power.
Channel 1 HS driver supply. This pin supplies the relative high side driver.
Connect through a capacitor (100nF typ.) to the PHASE1 pin and through a diode
to VCC (cathode vs. boot).
Device supply voltage. The operative supply voltage is 12V ±10%.
Filter with 1µF (Typ.) capacitor vs. GND.
All the internal references are referred to this pin. Connect it to the PCB signal
ground.
This pin is connected to the error amplifier output and is used to compensate the
control feedback loop.
This pin is connected to the error amplifier inverting input and is used to
compensate the control feedback loop.
