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 6 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.
