describe:

The MSK 4303 is a 10 amp, 3 phase bridge smart power motor drive hybrid with a 75 volt output

switch. The output switches are MOSFETs. This New Smart Power Motor Drive Hybrid is 5.0 Volt Input Logic

compatible. Undervoltage lockout shuts down the bridge when the supply voltage reaches an incomplete point

Turn on the output switch. Internal high side bootstrap supply from +VB supply

There is no need for 3 floating independent power supplies at all.

MSK 4303 is designed for +28V high voltage bus, +15V low power bus and +5V logic

Signal. Appropriate derating should be applied when designing the MSK 4303 into the system. high frequency layout

The technique of having a ground plane on a printed circuit board is the only method that should be used for circuit construction.

This will prevent pulse jitter caused by the current sense signal or excessive noise pickup on the error amplifier

Signal.

Ground planes for low-power circuits and high-power circuits should be kept separate. connect

At the bottom of the current sense resistor, between the COM pin and high power ground, the AV-, BV- and CV- pins are

Connect at this time. This is a critical path and large currents should not flow between the current sense and the current

com. Inductance in this path is kept to a minimum. The RC filter (shown at 2) will filter out the current

spikes and minimize detection noise for these circuits.

In the system shown, a PWM pulse of a pulsed current limiting scheme controlled by the motor controller is implemented.

When the motor speed is controlled by the PWM method, the low-side switch is required to be PWM pulsed

Bootstrap power supply for powering the high-side switch driver. The higher the PWM speed, the higher the current

Load drive power. The low-side PWM will prevent the high-side supply from drooping. A separate pin (+VB)

Used to connect an external floating power supply to power the bootstrap power supply.
