2 General Description

The MLX83202/MLX83203 family of pre-drivers is

designed to drive high-current N-type FET 3-phase

motor control applications.

The built-in EEPROM allows extensive configurability

of the pre-driver without the need for external

resistors and SPI interface programming. This

reduces the package pin count to only 32.

All output voltages are monitored for failure

conditions. The microcontroller is informed of the

failure condition via a fast serial interface.

The device comprises a current shunt amplifier, with

a high gain bandwidth (GBW), offering a fast settling

time with low noise. This makes the pre-drivers ideal

for precise torque control applications like e.g.

electrical power steering and brake by wire.

A combination of bootstrap and charge pump enables

driving

NFETs, with gate charges up to

400nC/NFET with a minimum of device self-heating.

The IC reset level below 4.5V allows for low-voltage

operation.
