SEMICONDUCTOR TECHNICAL DATA

Advance Information

34920

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.

2.8 Ω (TYP) QUAD H-BRIDGE

MOTOR DRIVER

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 bipolar step

motor driver. In step motor mode, both drivers are capable of being operated

in the quarter step mode.

In DC motor mode, both bridges in a driver are in parallel, providing 2.4 A

of drive current. In step motor mode, each bridge in a driver drives one phase.

Each phase is driven with a bipolar current mode drive.
