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.
