DESCRIPTION:
The MSK 4422 is a 20 Amp, 3 Phase Bridge Smart Power Motor Drive Hybrid with a 200 volt rating on the
output switches. The output switches are power MOSFETs with intrinsic fast-recovery diodes for the free-
wheeling currents of motor drives. This new smart power motor drive hybrid is compatible with 5V CMOS or
TTL logic levels. The internal circuitry prevents simultaneous turn-on of the in-line half bridge transistors with a
built-in 2μS deadtime to prevent shoot-through. Undervoltage lockout shuts down the bridge when the supply
voltage gets to a point of incomplete turn-on of the output switches. The internal high-side boot strap power
supply derived from the +15 volt supply completely eliminates the need for 3 floating independent power sup-
plies for the high-side drive. Current sense circuitry is provided to sense current from an external resistor to shut
down the bridge for overcurrent.

TYPICAL SYSTEM OPERATION
The MSK 4422 is designed to be used with a +100 volt high voltage bus, +15 volt low power bus and +5 volt
logic signals. Proper derating should be applied when designing the MSK 4422 into a system. High frequency layout
techniques with ground planes on a printed circuit board is the only method that should be used for circuit construc-
tion. This will prevent pulse jitter caused by excessive noise pickup on the current sense signal or the error amp
signal.
Ground planes for the low power circuitry and high power circuitry should be kept separate. The connection
between the bottom of the current sense resistor, VSS pin and the high power ground are connected at this point.
This is a critical path and high currents should not be flowing between the current sense and VSS. Inductance in this
path should be kept to a minimum. An RC filter (shown in 2 places) will filter out the current spikes and keep the
detected noise for those circuits down to a minimum.
In the system shown, two types of current limit are implemented. The first limit is a PWM pulse by pulse limit
controlled by the motor controller. A second absolute maximum limit is set up for the MSK 4422 which will com-
pletely shut off the bridge in the event that current limit is exceeded.
When controlling the motor speed by the PWM method, it is required that the low side switches be PWM pulsed
due to the bootstrap power supplies used to power the high side switch drives. The higher the PWM speed the higher
the current load on the drive supply. PWM of the low side will prevent sagging of the high side bootstrap supplies.
The logic signals coming from the typical motor controller IC are set up for driving N channel low side and P channel
high side switches directly and are usually 15 volt levels. Provision should be made for getting 5 volt logic signals to
the MSK 4422 of the correct assertion levels. Typically, the low side signals out of the controller are high active and
the high side are low active. Inverters are shown in the system schematic for the low side controller output.
