Description

The E910.68 integrated circuit is a universal ASSP for brush less DC motor control applications. The IC is a PWM Driver/Controller to drive 6 N-channel power-FETs. Each half-bridge of the device can be controlled by a separate digital input. The 6 driver outputs are designed to allow switching of up to 60kHz.

This E910.68 chip is designed for automotive application or general purpose motor drive application with supply voltages up to 27V. The E910.68 can be used in combination with a C to drive a BLDC motor by controlling the power FETs of three half bridges. 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 analogous voltages for external signal processing. The digital signals have a resolution of 30 of the electrical rotor angle.

This E910.68 chip can also generate the control signals for the power FETs internally. The setpoint of an external  regulator is forced via the SPI interface and the actual value of the motor speed is given back to the C. Configuration of programmable parameters is executed via an SPI. A sophisticated protection system prevents the external MOSFETs from damage.
