Description

The E910.88 integrated circuit is an universal ASSP for permanent magnet synchronous motor control applications. The  IC is a PWM controller to drive 6 N-channel power-FETs. The 6 driver outputs are designed to allow switching of up to 60kHz.

This E910.88 chip is designed for automotive application or general purpose motor drive application with supply voltages up to 27V. The E910.88 can control a PMS motor by controlling the power FETs of three half bridges. This chip generates the control signals for the power FETs internally. For speed regulation the setpoint is force via the PWM interface.

Sensor less rotor position detection of the BLDC motor is performed by observing the neutral point voltage of the motor. Position information of the rotor is provided as digital VirtuHall effect sensor signals or as analog voltages for external signal processing. The digital signals have a resolution of 30 of the electrical rotor angle. Configuration of programmable parameters is executed via an SPI. A sophisticated protection system prevents the external MOSFETs from damage.
