Product Introduction

Overview

The ADM1272-1ACPZ is a high-performance hot swap controller designed by Analog Devices Inc. This device enables the safe insertion and removal of circuit boards from live backplanes, making it ideal for high-voltage systems. It features advanced power monitoring, current, voltage, and power readback through an integrated 12-bit analog-to-digital converter (ADC), accessible via a PMBus interface. The ADM1272-1ACPZ is robust, capable of withstanding up to 120 V, and includes various protection mechanisms such as overvoltage (OV) and undervoltage (UV) protection, and programmable current limits.
