Datasheet for the ADM1070, a negative voltage hot swap controller for safe board insertion and removal from live -48 V backplanes with programmable current…
The ADM1070 is a negative voltage hot swap controller designed to allow a board to be safely inserted and removed from a live -48 V backplane. It achieves this by providing robust current limiting, protection against transient and nontransient short circuits, and overvoltage and undervoltage conditions. The device typically operates from a negative voltage of up to -80 V and can tolerate transient voltages of up to -200 V.

| Undervoltage Falling Threshold | 0.81 V to 0.91 V |
| Overvoltage Rising Threshold | 1.89 V to 2.05 V |
| Maximum Gate Voltage | 11 V to 13 V |
| Package Type | 6-Lead SOT-23 |
| Operating Temperature Range | -40 C to +85 C |
The device typically operates from a negative voltage of -77 V to -36 V.
The device can tolerate transient voltages of up to -200 V.
The part goes into shutdown after seven consecutive auto-restarts.
The part is available in a small 6-Lead SOT-23 package.
