A world fi rst in high-side current sensing

Confi gurable analog output and Digital bus, both for reporting on power measurement

Microchip’s PAC1921 is the world’s fi rst high-side current/power sensor to present power, current or voltage over a single output pin.

Using the 2-Wire digital bus to maximise data and diagnostic reporting, and the confi gurable analog output to minimise data latency, the PAC1921 increases fl exibility in high-speed power management applications.

The PAC1921’s analog output can be adjusted for 3V, 2V, 1.5V or 1V microcontroller inputs and measure system-load power from 0V to 32V.

• Flexible power measurement and diagnostics

• 39-bit accumulation register

• 128 times current gain confi guration

• 32 times voltage gain confi guration
