  • Product introduction

Automotive grade 3-phase isolator MOSFET drivers

A6861 是一个能够控制 MOSFET 的 N 通道功率MOSFET drivers,在相隔离应用中作为三相固态继电器连接。A6861 适用于必须满足 ASIL 要求的汽车系统。在安全性至关重要的应用中,电动机隔离是一项关键的安全要求,目前通过分立电路或继电器来解决。Allegro A2-SILTM 产品包括促成正确的系统设计的特定功能,允许用户达到 ASIL-D 系统评级。

A6861 有三个独立的浮动门级驱动输出,从而在存在高相电压转换率时,维持开 (ON) 状态的功率 MOSFET 超过完整供应范围。集成的电荷泵调节器提供必要的高于电池供应电压的电压,以在相电压等于电池电压时保持开 (ON) 状态的功率 MOSFET 持续运转。电荷泵将通过 100 kΩ 栅级电阻器为低至 4.5 V 的电池电压提供充足的门级驱动 (>7.5 V)。

三个门级驱动可以通过使用逻辑层级控制输入来独立控制。在典型的应用中,MOSFET 将在 8 μ 秒内 启动并在 1 μ 秒内关闭 。

欠压监视器检查泵供应电压是否足够高以确保 MOSFET 维持在安全的导电状态。

A6861 采用 16 引脚 TSSOP (LP) 封装,带外露隔热盘以增强散热。有关封装均为无铅产品,且引脚框采用 100% 雾锡电镀。
