Ground terminals.
Frequency-to-voltage open drain output. Every pulse from pin H
as a fixed and adjustable length pulse.
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.
Half bridge 3 source Pin. This pin must be connected together with pin
SENSE
the Inverting Input of the sense comparator is connected.
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 +5 V.
Chip enable. LOW logic level switches OFF all power MOSFETs.
If not used, it has to be connected to +5 V.
Current controller reference voltage.
Do not leave this pin open or connect to GND.
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 +5 V.
Bootstrap voltage needed for driving the upper power MOSFETs.
Half bridge 3 power supply voltage. It must be connected to the supply
voltage together with pin VS
Half bridge 1 and half bridge 2 power supply voltage. It must be connected to
the supply voltage together with pin VS
Charge pump oscillator 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.
Half bridge 1 and half bridge 2 source pin. This pin must be connected
together with pin SENSE
RC network pin. A parallel RC network connected between this pin and
ground sets the current controller OFF-Time.
