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 11kHz @ 3.0A
Synchronous rectification control of the high side MOSFETs
Low RDS(ON) outputs at high junction temperature (< 165m
Ω @
TA = 125
