ADM4210 is a hot swap controller that safely enables a printed circuit board to be removed and inserted to a live backplane. It features supply voltage control, current limit, fault protection, etc.
The ADM4210 is a hot‑swap controller that enables safe removal and insertion of printed‑circuit boards on a live backplane. It works with an external N‑channel MOSFET and uses an external sense resistor for adjustable analog current limiting and a charge‑pumped gate drive.
The device operates from 2.7 V to 16.5 V, includes undervoltage lockout, and is available in two versions: ADM4210‑1 with automatic retry and ADM4210‑2 with latch‑off on over‑current faults. It is supplied in a 6‑lead TSOT package and is pin‑compatible with LTC4210‑1/2.
| Operating Voltage Range (VEE) | 2.7 V to 16.5 V |
|---|---|
| Supply Current (typical) | 3.5 mA |
| Undervoltage Lockout (typical) | 2.65 V |
| Thermal Resistance (6‑Lead TSOT) | 169.5 °C/W |
The ADM4210 operates from 2.7 V up to 16.5 V.
