具有警报功能的 AEC-Q100、26V、三通道、13 位、I2C 输出电流/电压监控器 16-VQFN -40 to 125
The INA3221-Q1 is a three-channel, high-side current and bus voltage monitor with an I2C- and SMBUS-compatible interface. The INA3221-Q1 monitors both shunt voltage drops and bus supply voltages, in addition to having programmable conversion times and averaging modes for these signals. The INA3221-Q1 offers both critical and warning alerts to detect multiple programmable out-of-range conditions for each channel.
The INA3221-Q1 senses current on buses that can vary from 0 V to 26 V. The device is powered from a single 2.7-V to 5.5-V supply, and draws 350 µA typ of supply current. The INA3221-Q1 is specified over the operating temperature range of –40°C to +125°C. The I2C- and SMBUS-compatible interface features four programmable addresses.
