3 说明

DRV8316C-Q1 集成了三个 H 桥，具有 40V 的绝对最大电压和 95mΩ 的超低 RDS(ON)（高侧 + 低侧），可为 12V汽车级无刷直流电机提供高功率驱动能力。DRV8316C-Q1 提供集成电流检测功能，无需再使用外部检测电阻。DRV8316C-Q1 集成了电源管理电路，包括可用于为外部电路供电的电压可调节降压稳压器（3.3V/5V，200mA）和 LDO (3.3V/30mA)。

DRV8316C-Q1 提供了可配置的 6x 或 3x PWM 控制方案，可用于使用外部微控制器实现有传感器或无传感器磁场定向控制 (FOC)、正弦控制或梯形控制。DRV8316C-Q1 能够驱动高达 200kHz 的 PWM 频率。DRV8316C-Q1 可通过 SPI (DRV8316CR-Q1) 或引脚 (DRV8316CT-Q1) 进行高度配置。PWM 模式、压摆率、OCP 电平、电流检测增益是部分可配置的特性。

DRV8316C-Q1 集成了多种保护特性，包括电源欠压锁定 (UVLO)、过压保护 (OVP)、电荷泵欠压 (CPUV)、过流保护 (OCP)、过热警告 (OTW) 和过热关断 (OTSD)，目的是在出现故障事件时保护器件、电机和系统。故障状态通过 nFAULT 引脚指示。
