Sensor Input Single Ended Hall Effect Sensor Input 1.
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.
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.
RC Pin
RC Network Pin. A parallel RC network connected
between this pin and ground sets the Current
Controller OFF-Time.
Power Output Output 1
GND
Ground terminals. On PowerDIP24 and SO24
packages, these pins are also used for heat
dissipation toward the PCB. On PowerSO36 package
the slug is connected on these pins.
Open Drain
Output
Frequency-to-Voltage open drain output. Every pulse
from pin H1 is shaped as a fixed and adjustable length
pulse.
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.
