Advance Information
Document Number: MC33899
Rev. 4.0, 5/2010
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 R
DS(ON)
outputs at high junction temperature (< 165 mΩ @
TA = 125°C, VIGNP = 6.0 V)
• Outputs survive shorts to -1.0 V
• Pb-free packaging designated by suffix code VW
