Advance Information
Document Number: MC33899
Rev. 3, 6/2008
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
鈥?Drives inductive loads in a full H-Bridge configuration
鈥?Current mirror output signal (gain selectable via external resistor)
鈥?Short-circuit current limiting
鈥?Thermal shutdown (outputs latched off until reset via the SPI)
鈥?Internal charge pump circuit for the internal high side MOSFETs
鈥?SPI-selectable slew rate control and current limit control
鈥?Over-temperature shutdown
鈥?Outputs can be disabled to high-impedance state
鈥?PWM-able up to 11kHz @ 3.0A
鈥?Synchronous rectification control of the high side MOSFETs
鈥?Low R
DS(ON)
outputs at high junction temperature (< 165m惟 @
TA = 125擄C, VIGNP = 6.0V)
