It integrates an N-channel power MOSFET with a 50 mOhm max Rds(on), a charge pump to keep the gate driven when the output is on, and a full set of protection circuits — current limiting, over-temperature, and over-voltage — all in a PowerSSO-12 surface-mount package. ## 12 A output — the load budget and the thermal reality The 12 A continuous output rating is the absolute maximum at the device level. At 12 A, the I²R loss through the 50 mOhm Rds(on) hits 7.2 W, which the PowerSSO-12 package must dump into the PCB copper. The load supply range covers 5 V logic rails, 12 V automotive battery lines (including cold-crank dips down to 4.5 V), and 24 V industrial bus voltages. The device does not require a separate Vcc supply — the gate drive is derived from the load voltage via an internal charge pump, which means the driver works as a simple on/off switch controlled by a logic-level input. For a BOM line that still calls out this MPN, the only sourcing path is through independent distribution — surplus stock, new-old-stock, or broker channels. ## Protection set — what shuts it down and what brings it back The driver includes fixed current limiting, over-temperature shutdown, and over-voltage clamping. The Auto Restart feature means that after an over-temperature fault clears, the output re-enables automatically — useful for lamp or motor loads where a brief overload is expected, but something to account for in a design that expects latched-off behaviour.","metaTitle":"VN5050AJ-E VIPower high-side driver, 50 mOhm Rds(on)","metaDescription":"STMicroelectronics VN5050AJ-E single-channel high-side driver, 50 mOhm max Rds(on), 12 A output, PowerSSO-12.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"Obsolete","categoryPath":["Power Management (PMIC / Gate Driver)"],"specifications":{"Mfr":"STMicroelectronics","Series":"VIPower™","Package":"Tube","Features":"Auto Restart","Interface":"On/Off","Input Type":"Non-Inverting","Output Type":"N-Channel","Switch Type":"General Purpose","Rds On (Typ)":"50mOhm (Max)","Mounting Type":"Surface Mount","Package / Case":"PowerSSO-12","Product Status":"Obsolete","Voltage - Load":"4.5V ~ 36V","lifecycle_stage":"eol_hot","Fault Protection":"Current Limiting (Fixed), Over Temperature, Over Voltage","Number of Outputs":"1","Base Product Number":"VN5050","Output Configuration":"High Side","Ratio - Input:Output":"1:1","Operating Temperature":"-40°C ~ 150°C (TJ)","Current - Output (Max)":"12A","Supplier Device Package":"PowerSSO-12™","Voltage - Supply (Vcc/Vdd)":"Not Required"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$2.7200","priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/98882e2ffc86390bc22d31007880e028.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/VN5050AJ-E/alternatives.json"},"ai":{"faq":[{"question":"What is the Rds(on) of the VN5050AJ-E?","answer":"The maximum Rds(on) is 50 mOhm, specified at 25°C junction temperature.
