GENERAL DESCRIPTION

The EV6536-U-00A is the evaluation board for

the MP6536, a three-phase BLDC motor driver.

It accepts PWM modulated inputs for operation.

The MP6536 features a low current shutdown

mode, standby mode, input under voltage

protection, current limit, thermal shutdown and

fault flag signal output. All channels of drivers

interface with standard logic signals.

The MP6536 is available in a 40 lead QFN 5X5

package.
