• Manufacturer Part Number: MPC17559EP/R2
• Description: Micromotor Driver with Dual 3-Phase and Dual H-Bridge Outputs
• Manufacturer: FREESCALE [Freescale Semiconductor, Inc]

multiple motor driver IC ideal for portable electronic
applications containing two brushless DC motors plus two DC
brush motors (or plus one bipolar step motor). The control
logic translates the input signals to the gate-driver circuitry
while providing cross-conduction suppression.

and VI1) set the driver states (UO1, VO1, and WO1) in
accordance with the logic set force defined in
page 11. Typically these inputs are supplied from an MCU or
a digital signal processor (DSP) to provide the phasing of the
currents applied to a brushless DC motor.
THREE-PHASE DRIVER CHANNEL 1 OUTPUT

VO1, and WO1) drive a three-phase motor, as well as supply
the peak currents with applied ON resistance (R
THREE-PHASE DRIVER CHANNEL 1 PHASE
POWER GROUND (PGNDW1 AND PGNDUV1)
terminals (PGNDw1 and PGNDuv1) are ground terminals for
three-phase driver channel 1. PGNDw1 is a ground for W
phase driver, and PGNDuv1 is a ground for U and V phase
driver. PGNDw1 and PGNDuv1 are physically connected in
the IC in order to reduce internal resistance.
THREE-PHASE DRIVER CHANNEL 1 PHASE
POWER SUPPLY (VMVW1 AND VMU1)
terminals (VMvw1 and VMu1) are power supply terminals for
three-phase driver channel 1. VMvw1 is a power supply for V
and W phase driver, and VMu1 is a power supply for U phase
driver. VMvw1 and VMu1 are phyically connected in the IC in
order to reduce internal resistance.
THREE-PHASE DRIVER CHANNEL 2 INPUT
(UI2, VI2, AND WI2)
and WI2) set the driver states (UO2, VO2, and WO2) in
accordance with the logic set force in
inputs are supplied from an MCU or DSP to provide the
phasing of the current applied to a brushless DC motor.
