EVAL-CN0274-SDPZ

EVAL-CN0274-SDPZ is a CN0274 circuit evaluation board that provides an ultralow-power, 3-axis, motion-activated power switch capable of controlling up to 1.1A of load current. It is designed for applications where extended battery life is critical, consuming less than 300nA when the switch is off and less than 3µA when it is on. The circuit uses the ADXL362, an ultralow-power 3-axis accelerometer, to monitor acceleration and control the high-side switch based on the presence or absence of motion. The ADXL362 provides 12-bit resolution, selectable ±2 g, ±4 g, and ±8 g ranges, continuous sampling, and an integrated temperature sensor. The ADP195 high-side load switch operates from 1.1V to 3.6V, features reverse-current protection, and uses a low on-resistance P-channel MOSFET capable of supporting over 1.1 A of continuous load current. The circuit is suitable for wireless sensors, metering devices, home healthcare, and other portable applications.

• Evaluation board connects to SDP-B controller board (EVAL-SDP-CB1Z) through 120-pin connector
