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.
Power Supply
Half Bridge 3 Source Pin. This pin must be connected
together with pin SENSEA to Power Ground through a
sensing power resistor. At this pin also the Inverting
Input of the Sense Comparator is connected.
Logic Input
Selects the direction of the rotation. HIGH logic level
sets Forward Operation, whereas LOW logic level sets
Reverse Operation.
If not used, it has to be connected to GND or +5V..
Logic Input
Chip Enable. LOW logic level switches OFF all Power
MOSFETs.
If not used, it has to be connected to +5V.
Logic Input Current Controller Reference Voltage.
Do not leave this pin open or connect to GND.
Logic Input
Brake Input pin. LOW logic level switches ON all High
Side Power MOSFETs, implementing the Brake
Function.
If not used, it has to be connected to +5V.
Supply Voltage Bootstrap Voltage needed for driving the upper Power
MOSFETs.
Power Output Output 3.
Power Supply Half Bridge 3 Power Supply Voltage. It must be
connected to the supply voltage together with pin VSA.
