APPLICATION NOTES
MSK 4204RH PIN DESCRIPTIONS
+VCC - Is the low voltage supply for powering internal
logic and drivers for the lowside and highside MOSFETS.
The supplies for the highside drivers are derived from this
voltage. Optimum operation occurs with VCC set at 15V.
AV+, BV+ - Are the high voltage H-bridge supply pins.
The MOSFETS obtain the drive current from these supply
pins. The voltage is limited by the drive IC. The MOSFETS
are rated at 100 volts. Proper by-passing to GND with
sufficient capacitance to suppress any voltage transients,
and ensure removal of any drooping during switching,
should be done as close to the pins on the hybrid as pos-
sible.
AØ - Are the output pins for one half of the bridge. In-
creasing the input voltage causes increasing duty cycles
at this output.
GND - Is the return connection for the input logic and
Vcc.
INPUT - Is an analog input for controlling the PWM pulse
width of the bridge. A voltage higher than 7.5V will pro-
duce greater than 50% duty cycle pulses out of OUTPUT
A. A voltage lower than 7.5V will produce greater than
50% duty cycle pulses out of OUTPUT B.
SHUTDOWN - Is the connection for disabling all 4 output
switches. SHUTDOWN high overrides all other inputs.
When taken low, everything functions normally. An inter-
nal pullup to Vcc will keep SHUTDOWN high if left uncon-
nected. This pin should be grounded if not used.
BØ - Are the output pins for the other half of the bridge.
Decreasing the input voltage causes increasing duty cycles
at this output.
AV- - Are the connections for the bottom of the A half
bridge. This can have a sense resistor connection to the
V+ return ground for current limit sensing, or can be con-
nected directly to ground. The maximum voltage on these
pins is ±5 volts with respect to GND.
BV- - Are the connections for the bottom of the B half
bridge. This can have a sense resistor connection to the
V+ return ground for current limit sensing, or can be con-
nected directly to ground. The maximum voltage on these
pins is ±5 volts with respect to GND.
