ISL28025开发板套件编程器的评估演示板及套件规格书PDF中文资料

The ISL28025 is a bidirectional high-side and low-side digital

current sense and voltage monitor with a serial interface. The

device monitors power supply current and voltage and

provides the digital results along with calculated power. The

ISL28025 provides tight accuracy of less than 0.1 for both

voltage and current monitoring.

The VCC power can either be externally supplied or internally

regulated, which allows the ISL28025 to handle a

common-mode input voltage range from 0V to 60V. The wide

range permits the device to handle telecom, automotive and

industrial applications with minimal external circuitry.

Fault indication includes Bus Voltage window and overcurrent

fast fault logic indication. The ISL28025 includes an integrated

temperature sensor for monitoring.

The ISL28025 serial interface is PMBus compatible and

operates down to 1.2V voltage. It draws an average current of

just 1.3mA and is available in the space saving 16 ball WLCSP

package. The parts operate across the full industrial

temperature range from -40°C to +125°C.
