www.DataSheet4U.com Freescale Semiconductor Advance Information Document Number: MC34920 Rev.

2.0, 1/2007 2.8 Ω (Typ) Quad H-Bridge Motor Driver The 34920 is a multifunctional analog ASIC.

The 34920 integrates two circuits, four H-bridge drivers, a reset circuit in a single IC, and two DC/DC switching voltage regulators.

Input voltage is 21 V to 42 V DC.

Each motor of the two driver blocks can be configured as either a DC motor driver with pulse width modulation (PWM)-control or a single bipo
