Abstract MLX80153
OTP Full Bridge motor controller
1 Features Overview
 Integrated motor controller
o Full Bridge NFET predriver
 Double Charge pump with programmable NFET gate voltage
 HS NFET and Low Side NFET control
 Synchronous rectification with programmable dead time
o 3 high voltage Wake up capable IO’s on rising and falling edge
o 3 low voltage IO’s with multiple configuration options
o Automotive Supply regulator
 Standard Operating range [7, 18]V, Tj=[-40, 125]C
 Extended operating range [4.5, 28]V, Tj = [-40, 150]C
 45V Load dump protected
 Sleep current <50uA
o Autosequence 10bit ADC with DMA avoids need for MCU interrupts to handle
sampling. Multiple input channels
 Battery (VSUP) and motor supply (VDRAIN)
 Internal Temperature sensor (+/-15K)
 All IO’s can be configured as analog inputs.
 Single shot NTC measurement with 3.3V ADC reference voltage.
o Low Side Shunt amplifier with
 Programmable gain,
 Programmable Overcurrent protection and Current limiting levels
 Synchronised measurements with programmable blanking time.
 16bit Microcontroller
o Two 16 bit timers for PWM communication
o 16 bit core timer
o 512 Byte RAM
o 128 Byte data EEPROM
o 16kB OTP Program memory (Flash for engineering samples only).
