SA53HU中文资料60V, 3A PWM Amplifier with Integrated Gate Driver数据手册APEX规格书

描述 Description

The SA53 is a low cost, 3A (10A PEAK), 60V pulse width modulation (PWM) motor driver IC. As a monolithic, single package solution, the SA53 provides a high level of integration for driving brush-type DC motors in the market space between lower current devices and higher cost drivers operating on 400+ voltage supplies.

A seamless digital interface is possible with the SA53 by partnering with either a MCU or DSP. Individual control of both the top side and the bottom side output FETs is allowed via direct signals from the processor.

Thermal and short circuit monitoring for the SA53 is provided, which generates fault signals for the microcontroller to take appropriate action. Additionally, cycle-by-cycle current limit offers user programmable hardware protection independent of the microcontroller. Output current is measured using an innovative low loss technique.

Housed in a 44-pin HSOP package with integrated heat slug, the SA53HU provides balance between excellent thermal performance with the advantages of a low profile surface mount package.
