It integrates auto-restart after a fault clears, fixed current limiting, open-load detection, and over-temperature shutdown — reducing the external protection component count around the load. ## 80 mOhm on-resistance and 1.6 A continuous rating With a typical Rds(on) of 80 mOhm, the IPS521G drops about 128 mV at 1.6 A — manageable in a 5.5 V to 35 V load supply range. The 1.6 A maximum output is the continuous limit; pulsed loads can exceed this within the SOA, but the fixed current-limiting threshold clamps the peak. The 8-SOIC package (0.154-inch body width) dissipates the conduction heat through the leadframe. At 1.6 A continuous, the power loss is roughly 205 mW; the junction-to-ambient thermal resistance of the SOIC-8 (~110 °C/W typical) keeps the die below the 150 °C maximum junction temperature in still air up to about 125 °C ambient. ## Fault protection and auto-restart behaviour The auto-restart feature means the switch cycles on and off after an over-temperature or current-limit fault, re-trying the load at a low duty cycle until the fault clears. This is useful for driving lamps or motors where a temporary overload is expected and automatic recovery is preferred over latch-off. Open-load detection flags a disconnected output when the switch is off — a diagnostic signal for the system controller. The non-inverting On/Off interface simplifies logic-level drive: a high on the input turns the output on, no external level shifter needed.","metaTitle":"IPS521G High-Side Power Switch, 80 mOhm, 1.6 A, Obsolete","metaDescription":"IPS521G high-side N-channel switch, 80 mOhm Rds(on), 1.6 A output, 5.5-35 V load, auto restart, fault protection.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"Obsolete","categoryPath":["Power Management (PMIC / Gate Driver)"],"specifications":{"Mfr":"Infineon Technologies","Series":"-","Package":"Tube","Features":"Auto Restart","Interface":"On/Off","Input Type":"Non-Inverting","Output Type":"N-Channel","Switch Type":"General Purpose","Rds On (Typ)":"80mOhm","Mounting Type":"Surface Mount","Package / Case":"8-SOIC (0.154\\\", 3.90mm Width)","Product Status":"Obsolete","Voltage - Load":"5.5V ~ 35V","lifecycle_stage":"eol_hot","Fault Protection":"Current Limiting (Fixed), Open Load Detect, Over Temperature","Number of Outputs":"1","Base Product Number":"IPS521","Output Configuration":"High Side","Ratio - Input:Output":"1:1","Operating Temperature":"-40°C ~ 150°C (TJ)","Current - Output (Max)":"1.6A","Supplier Device Package":"8-SOIC","Voltage - Supply (Vcc/Vdd)":"Not Required"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$3.1800","priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/8f611b1ad401ba9153b7ee7ac26ab520.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/IPS521G/alternatives.json"},"ai":{"faq":[{"question":"Is IPS521G obsolete?","answer":"Yes, the IPS521G is listed as obsolete by Infineon.
