ADM1273-1ACPZ

Overview

The ADM1273-1ACPZ is a single-channel hot swap voltage controller manufactured by Analog Devices Inc. It operates within an input supply voltage range of 16 V to 80 V and features a low quiescent current of 1 nA. The device is housed in a 48-lead LFCSP package designed for surface mount installation. It supports an extended operating temperature range from -40°C to +105°C. This component integrates protection mechanisms suitable for high-voltage power distribution systems, ensuring reliable board insertion and removal without disrupting the main bus.

Feature Summary

Integrates precise current limit control with adjustable threshold settings for robust overcurrent protection during hot swap events.
Features fast fault response times to isolate damaged boards quickly, minimizing impact on the shared power bus infrastructure.
Includes built-in soft-start functionality to manage inrush currents smoothly during initial power-up sequences.

Applications

High-voltage backplane power distribution in telecommunications equipment
Server blade insertion and removal management in data centers
Industrial control system modular power supply units

Procurement Notes

Verify the specific suffix 'ACPZ' corresponds to the lead-free LFCSP-48 package variant when sourcing. Confirm that the required input voltage range aligns with your system's 16 V to 80 V operational limits. Ensure PCB layout accommodates the thermal requirements of the 48-lead package for optimal heat dissipation during continuous operation.

Selection Notes

Select this controller for applications requiring high-voltage tolerance up to 80 V with minimal standby power consumption. Consider the 48-lead LFCSP footprint for space-constrained designs needing multiple protection channels or complex sequencing. Evaluate the need for adjustable current limits versus fixed thresholds based on load characteristics.

Part Context

This component belongs to the ADM1273 family of hot swap controllers, designed for high-reliability power management. It complements other Analog Devices PMIC solutions by providing specialized protection for modular systems. The series emphasizes ease of integration into existing high-voltage architectures while maintaining strict safety standards for personnel and equipment.
