The ADM1073 hot-swap controller was developed as a result of rigorous research, development and testing in response to the growing demand for highly stable and flexible hot-swap capabilities

Hot-swap controllers enable safe board insertion and removal from a live 48V backplane. The ADM1073 is loaded with new and enhanced features critical for seamless hot-swap applications, including: industry leading current-limit accuracy; improved pulsewidth modulation (PWM) accuracy and flexibility; dual overvoltage (O/V) and undervoltage (U/V) pins with variable hysteresis; programmable soft starting of the current profile; time based foldback (TBF) for additional field effect transistor (FET) protection; and five additional logic I/O flags (including shutdown and restart).

The new device incorporates precise, robust current limiting and protection against transient and nontransient short circuits O/V and U/V conditions.

It operates from a negative voltage of up to 80V and can tolerate transient voltages of up to 200V.

The ADM1073 constantly monitors the load current to ensure that it remains less than a level programmed by an external sense resistor.

Dynamic control of a FET in the power path allows this current to maintain a safe level at all times.

Inrush current is accurately controlled at initial connection.

This control, combined with the flexible limited consecutive retry PWM scheme and a new TBF feature offers the highest possible level of short-circuit protection.

The versatility of the ADM1073 makes it ideal for a broad range of applications, including central office switches, basestations, DSL access multiplexers, power supply controls, circuit breakers, high-availability servers and 48V distributed power systems.

The ADM1073 comes in a 14-lead TSSOP.

The price per unit in 1000-piece quantities is $2.00.

The controllers are sampling today, with production quantities available shortly.
