B6 bridge driver with integrated LIN2.1 or PWM interface

Complete solution with voltage regulator, watchdog, reset and wake-up functions
Elmos E523.01 (PresseBox) (Stutensee (Germany), ) Gleichmann Electronics now offers the E523.01 motor driver from Elmos Semiconductor. This new IC controls up to three external NMOS half bridges for driving BLDC motors or DC motors. The E523.01 features a LIN2.1 compatible interface as well as a PWM interface with data preprocessing.

For operation with an external microprocessor, the E523.01 provides a 3.3 V or 5.0 V power supply, a reset function and a configurable window watchdog. Other features of the E523.01 include a low standby current drain of <50 µA, an integrated motor current measuring amplifier and an optionally available external boost transistor for the integrated voltage regulator. With the help of this external transistor, the microprocessor can be supplied with higher current or the internal power loss of the E523.01 can be minimized even further.

The dead time between the high-side and low-side FETs can be very precisely adjusted via SPI interface for an optimized control. A short-circuit detection at all external FETs as well as voltage, current and temperature monitoring provide the greatest possible safety.

The E523.01 is suited for use in automotive and industrial drives in a voltage range up to 28 V. In addition to the E523.01, the E523.11 with only a PWM interface is also available. Both versions are available in QFN44L7 and QSOP44 packages.
