It lets you insert a board into a live backplane without glitching the supply rail, then read back the load current and voltage digitally. The controller itself handles the inrush limiting and fault response; there is no internal pass FET, so you size the external N-channel MOSFET to match your load current. Supply range runs from 3.15 V up to 16.5 V. The operating temperature range of -40°C to 85°C makes it suitable for industrial enclosures, outdoor telecom cabinets, and factory-floor equipment that sees seasonal temperature swings. ## What the ratings mean for your BOM The 1.7 mA supply current is the controller's own draw — it does not include the gate drive charge for the external FET. Budget that into your housekeeping rail; it is low enough that a small linear regulator from the backplane supply is fine. Programmable features include current limit, fault timeout, and turn-on voltage. The latched fault behaviour holds the FET off after a fault until you cycle the supply or the ON pin, which is the safer choice for systems that should not auto-retry into a short. The 10-MSOP package (3.00 mm width) is compact enough for mezzanine cards and blade servers. It is a surface-mount part, so plan for reflow or a hot-air station — not a field-swap candidate without the right kit.","metaTitle":"ADM1178-2ARMZ-R7 Hot Swap Controller, Monitor, 3.15V-16.5V","metaDescription":"ADI ADM1178-2ARMZ-R7 hot swap controller with I²C monitoring, 3.15V to 16.5V supply, -40°C to 85°C range, 10-MSOP.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":"ROHS3 Compliant","productStatus":"Active","categoryPath":["Analog & Data Acquisition"],"specifications":{"Type":"Hot Swap Controller, Monitor","Package":"Tape & Reel (TR); Cut Tape (CT)","Features":"I²C, Latched Fault, UVLO","Applications":"General Purpose","Mounting Type":"Surface Mount","Package / Case":"10-TFSOP, 10-MSOP (0.118\\\", 3.00mm Width)","lifecycle_stage":"eol_hot","Current - Supply":"1.7 mA","Voltage - Supply":"3.15V ~ 16.5V","Internal Switch(s)":"No","Number of Channels":"1","Operating Temperature":"-40°C ~ 85°C","Programmable Features":"Current Limit, Fault Timeout, Turn On Voltage","Supplier Device Package":"10-MSOP"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$8.35","stockQuantity":0,"priceTiers":[{"qty":1,"price":"$8.35000","currency":"USD"},{"qty":10,"price":"$7.54300","currency":"USD"},{"qty":25,"price":"$7.19280","currency":"USD"},{"qty":100,"price":"$6.24530","currency":"USD"},{"qty":250,"price":"$5.96464","currency":"USD"},{"qty":500,"price":"$5.43832","currency":"USD"},{"qty":1000,"price":"$4.96500","currency":"USD"}]},"links":{"datasheetUrl":"https://cdn.icboms.com/7825bebfb5bf724d9396c5a37c78b56e.pdf","sourceUrl":null},"ai":{"faq":[{"question":"Does ADM1178-2ARMZ-R7 have an I2C interface?","answer":"Yes, it includes an I²C interface for reading back load current and supply voltage.
