Technical Data
Dual High-Side Switch for
H-Bridge Applications
This 33486A is a self-protected dual 15 mhigh-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 mHigh-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

This is the ground terminal of the device.
The Current Sense terminal delivers a ratio amount of the sum of the
high-side currents.
These are the device input terminals that directly control their associated
outputs. Each input terminal has an internal active pull-down so that the
input terminal will not float if disconnected.
Each terminal must be connected to one gate of an external low-side
MOSFET.
Terminals 5, 6, 7, and 8 are the source of the Output Channel 1 15 m
high-side MOSFET1.
These terminals are not used.
Terminals 13, 14, 15, and 16 are the source of the Output Channel 2
15 mhigh-side MOSFET2.
The status output goes low when a fault mode is detected. It is an open
drain with an internal clamp at 6.0 V. An external pull-up resistor
connected to VDD (5.0 V) is needed.
This logic input enables control of the device. (Wake logic LOW = Sleep
Mode, Wake logic HIGH = full operation.) The WAKE terminal has a pull-
down resistor.
The backside TAB is connected to the power supply of the 33486A.
