Programmable H-Bridge

Power IC

The 33899 is designed to drive a DC motor in both forward and

reverse shaft rotation under pulse-width modulation (PWM) control of

speed and torque. A current mirror output provides an analog

feedback signal proportional to the load current. A serial peripheral

interface (SPI) is used to select slew rate control, current

compensation limits and to read diagnostic status (faults) of the H-

Bridge drive circuits. SPI diagnostic reporting includes open circuit,

short-circuit to VIGNP, short-circuit to ground, die temperature range,

and under-voltage on VIGNP.

Features

• Drives inductive loads in a full H-Bridge configuration

•

Current mirror output signal (gain selectable via external resistor)

• Short-circuit current limiting

•

Thermal shutdown (outputs latched off until reset via the SPI)

• Internal charge pump circuit for the internal high side MOSFETs

• SPI-selectable slew rate control and current limit control

• Over-temperature shutdown

• Outputs can be disabled to high-impedance state

• PWM-able up to 11 kHz @ 3.0 A

• Synchronous rectification control of the high side MOSFETs

•

Low RDS(ON) outputs at high junction temperature (< 165 m

Ω @

TA = 125

°C, VIGNP = 6.0 V)

•

Outputs survive shorts to -1.0 V

• Pb-free packaging designated by suffix code VW
