describe:

The MSK 4354 is a 10 Amp, 3 Phase Bridge Smart Power Motor Drive Hybrid with a 600 Volt output

switch. The output switches are insulated gate bipolar transistors (IGBTs). Freewheeling diodes are fast

Recovery Epitaxial Diode (FRED) provides IGBT matched current capability with excellent performance

Reverse recovery time. This new smart power motor drive hybrid is compatible with 5.0 volt input logic. undervoltage

Locking turns off the bridge when the supply voltage reaches the point where the output switch is not fully turned on. Should

Internal high-side bootstrap supply from +VB supply completely eliminates the need for 3 floats

MSK 4354 is designed for +270 volt high voltage bus, +15 volt low power bus and +5 volt

logic signal. When designing the MSK 4354 into the system, it should be derated appropriately. 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
