Dual High-Side Switch for

H-Bridge Applications

This 33486A is a self-protected dual 15 m

Ω high-side switch that

incorporates a dual low-side switch control and protection features.

This device is used to replace electromechanical relays and discrete

devices in power management applications. It is designed for typical

DC-motor control in an H-Bridge configuration.

The 33486A can directly interface with a microcontroller for control

and diagnostic functions. It is PWM-capable and has a self-adjusting

switching speed for minimizing electromagnetic emission.

Features

•Dual 15 m

Ω High-Side Switch with Dual Low-Side Control

•10 A Nominal DC Current

•8.0 V to 28 V Operating Voltage with Standby Current < 10

µA

• High-Side Overtemperature Protection

• High-Side and Low-Side Overcurrent Protection

• Current Recopy to Monitor High-Side Current

• PWM Capability up to 30 kHz

• Common Diagnostic Output

• Overvoltage and Undervoltage Detection

• Cross-Conduction Management
