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 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.
