  • Product Introduction

A3908 是一款低电压双向直流Motor drive,典型输入电压范围为 3 至 5.5 V,而输出电流高达 500 mA。独特的全桥式输出整合源端线性操作,可确保电动机线圈的恒定电压供应。稳压输出可最大限度地减小因 I  ×  RDS (On)变化及电池电压公差导致的电动机电压变化。

逻辑输入引脚可控制电动机的旋转方向、制动及待机(Current drive的可选 PWM。内部保护电路拥有过热关机、欠压锁定及交叉电流(击穿)保护功能。

The A3908 is available in a 2 mm × 2 mm (0.55 mm nominal height), 8-pin DFN package with an exposed thermal gasket (package suffix EE). The small package is lead-free and has a pin frame with 100% matte tin plating.
