E523.01: B6 bridge driver with voltage regulator, watchdog, reset, and
wake-up functions

With the E523.01, ELMOS presents an EC motor driver with all the functions
required for the configuration of a complete, low-cost system. Apart from
the high-performance bridge driver, for communication purposes the
semiconductor features a LIN2.1 compatible interface as well as a PWM
interface with data pre-processing. For an external microprocessor,
optional 3.3 or 5.0V voltage supply (70mA), reset, and a configurable
window watchdog are provided. The E523.01 is suited for use in automotive
as well as industrial applications; target applications range from radiator
and blower fans and gas, hydraulic, oil and water pumps to wiper
applications as well as industrial motors (fans, pumps) up to a voltage of
28V.

The motor driver powers 3 external NMOS half-bridges for BLDC or DC motors,
optionally with 3 or 6 PWM input signals. Small loads can be directly
controlled. The dead time between the high-side and low-side FETs can be
adjusted most precisely via SPI interface, thus enabling the optimized
control of the power drivers. Elaborate diagnostic and protective features
such as short-circuit detection at all external FETs and voltage, current
and temperature monitoring provide for the best possible safety.

Due to its very low power loss and the efficient QFN package, the IC can
also be used in high-temperature environments. Other characteristics of the
E523.01 are the low standby current drain (< 50µA), the motor current
measuring amplifier, and the optional boost transistor for the integrated
voltage regulator. With the help of this external transistor, the
microprocessor can be supplied with higher current levels or the internal
power loss of the E523.01 can be minimized even further.

In addition to the E523.01, the E523.11 is available with just a PWM
interface. Both products can be supplied in the QFN44L7 or the QSOP44
package.
