Open Drain
Output
Overcurrent Detection and Thermal Protection pin. An
internal open drain transistor pulls to GND when an
overcurrent on one of the High Side MOSFETs is
detected or during Thermal Protection.

SENSEA
Power Supply
Half Bridge 1 and Half Bridge 2 Source Pin. This pin
must be connected together with pin SENSEB to
Power Ground through a sensing power resistor.

RCOFF
RC Pin
RC Network Pin. A parallel RC network connected
between this pin and ground sets the Current
Controller OFF-Time.

are
also
used
for
heat
dissipation toward the PCB. On PowerSO36 package
the slug is connected on these pins.

TACHO
Open Drain
Output
Frequency-to-Voltage open drain output. Every pulse
from pin H1 is shaped as a fixed and adjustable length
pulse.

RCPULSE
RC Pin
RC Network Pin. A parallel RC network connected
between this pin and ground sets the duration of the
Monostable Pulse used for the Frequency-to-Voltage
converter.
