MSK 4202RH PIN DESCRIPTIONS
Rev. A 5/00

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. The +5V regulator also gets its supply voltage
from this pin.
V+
- Is the high voltage H-bridge supply. The MOSFETS
obtain the drive current from this supply pin. The voltage
on this pin is limited by the drive IC. The MOSFETS are
rated at 100 volts. Proper by-passing to GND with suffi-
cient capacitance to suppress any voltage transients, and
to ensure removing any drooping during switching, should
be done as close to the pins on the hybrid as possible.
OUTPUT A
- Is the output pin for one half of the bridge.
Increasing the input voltage causes increasing duty cycles
at this output.
OUTPUT B
- Is the output pin for the other half of the
bridge. Decreasing the input voltage causes increasing
duty cycles at this output.
RSENSE A
- Is the connection 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 this
pin is ±2 volts with respect to GND.
RSENSE B
- Is the connection 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 this
pin is ±2 volts with respect to GND.
HEN
- Is the connection for enabling the high side output
switches. When taken low, HEN overrides other inputs
and the high side switches remain off. When HEN is high,
everything functions normally. An internal pullup to Vcc
will keep HEN high if left unconnected.
INPUT
- Is an analog input for controlling the PWM pulse
width of the bridge. A voltage higher than 2.5V will pro-
duce greater than 50% duty cycle pulses out of OUTPUT
A. A voltage lower than 2.5V will produce greater than
50% duty cycle pulses out of OUTPUT B.
DIS
- Is the connection for disabling all 4 output switches.
DIS high overrides all other inputs. When taken low, ev-
erything functions normally. An internal pullup to Vcc will
keep DIS high if left unconnected. This pin should be
grounded if not used.
GND
- Is the return connection for the input logic and
Vcc.
+5V OUT-
Is the output of the internal linear regulator.
This pin should be bypassed to GND using a 4.7μF tanta-
lum capacitor and a 0.1μF ceramic capacitor . This pin
can supply up to 500mA of output current for powering
other external circuitry, depending on case temperature
and input voltage.
CT-
Is a connection to the internal ramp generator. An
external capacitor can be connected from this pin to GND
to lower the PWM frequency. The following chart is use-
ful to determine a capacitor for a lower PWM frequency.
