MIC4604

Overview

TopologyMotor Drive
Input voltage18-63 V
IC revision1

Description

The "e-Bike Traction Motor Control" targets high-performance,low power and cost-effective motor controlapplications; for example, applications for e-mobility(e-bikes). The "e-Bike Traction Motor Control" can driveBLDC/PMSM motors of up to 1 kW peak power and upto 60A peak-to-peak phase currents. The input voltagerange is between 18V and 63V, covering the applicationspowered from battery strings of up to 15S (Li-Ioncells).For maximum battery efficiency and lower noise, aField-Oriented Control (FOC) algorithm is used to controlthe motor speed and torque. Two rotor positionfeedback options are available, including three 120°spaced Hall sensors on motors so equipped, or sensorlesscurrent feedback using up to three shunt resistorsfor motors without Hall sensors.

Features

  • +18V to +63V VBUS Input Voltage range (coverup to 15S batteries setup)
  • Maximum output power: 1000W
  • 130A peak-to-peak (for maximum 120 seconds)motor phase current
  • Low-side shunt resistors on each inverter phasefor current measurement (1 mΩ)
  • PWM switching frequency range 8 kHz - 20 kHz(typical 16 kHz)
  • Six N-Channel MOSFETs with low RDS(ON) (typical1.4 mΩ)
  • XT30 - type connector for convenient connectionwith the battery packs
  • Support for Field-Oriented Control (FOC) with Hallsensors or with motor phase current shunt resistors
  • PICkit™ debugger/programmer interface
  • Support for on board temperature measurement(MPC9700)
  • Auxiliary connectors (for custom functions likeCAN, I2C, UART, THROTTLE (acceleration), programming/debug, etc.)

Typical applications

  • E-Bike Motor Driver
