It is a general-purpose load switch for portable, battery-powered, and embedded systems where a small footprint and integrated protection matter. The switch is self-powered — no separate Vcc supply needed — and includes a status flag output plus fixed current limiting and over-temperature shutdown. ## 500 mA output with 400 mOhm on-resistance At 500 mA the 400 mOhm typical Rds(on) yields conduction loss. The fixed current limit is non-adjustable, so the load must stay within the 500 mA absolute maximum. ## Fault protection and status flag Built-in current limiting (fixed, not adjustable) and over-temperature protection cover the common fault cases — shorted load or excessive ambient. The status flag output (open-drain, active low) signals over-current or thermal shutdown to the host controller. Because the flag is a logic output, it needs a pull-up resistor to the host supply (not the load rail). No separate Vcc pin means the switch is always ready when the load rail is present; there is no enable threshold to sequence. ## Lifecycle and sourcing The LM34904ITM/NOPB is confirmed active with no last-time-buy notice. ROHS3 compliant. No official second source or pin-compatible alternate is listed in the record.","metaTitle":"LM34904ITM/NOPB Power Switch, 500 mA, 6-DSBGA","metaDescription":"Texas Instruments LM34904ITM/NOPB high-side N-channel power switch, 500 mA max, 2.8-5.3 V load, 400 mOhm Rds(on), active status, ROHS3.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":"ROHS3 Compliant","productStatus":"Active","categoryPath":["Analog & Data Acquisition"],"specifications":{"Package":"Tape & Reel (TR); Cut Tape (CT)","Features":"Status Flag","Interface":"On/Off","Input Type":"Non-Inverting","Output Type":"N-Channel","Switch Type":"General Purpose","Rds On (Typ)":"400mOhm","Mounting Type":"Surface Mount","Package / Case":"6-WFBGA, DSBGA","Voltage - Load":"2.8V ~ 5.3V","lifecycle_stage":"eol_hot","Fault Protection":"Current Limiting (Fixed), Over Temperature","Number of Outputs":"1","Output Configuration":"High Side","Ratio - Input:Output":"1:1","Operating Temperature":"-40°C ~ 85°C (TA)","Current - Output (Max)":"500mA","Supplier Device Package":"6-DSBGA","Voltage - Supply (Vcc/Vdd)":"Not Required"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$1.06","stockQuantity":0,"priceTiers":[{"qty":1,"price":"$1.06000","currency":"USD"},{"qty":10,"price":"$0.95100","currency":"USD"},{"qty":25,"price":"$0.90240","currency":"USD"},{"qty":100,"price":"$0.74120","currency":"USD"},{"qty":250,"price":"$0.69280","currency":"USD"},{"qty":500,"price":"$0.61226","currency":"USD"},{"qty":1250,"price":"$0.48336","currency":"USD"},{"qty":2500,"price":"$0.45600","currency":"USD"}]},"links":{"datasheetUrl":"https://cdn.icboms.com/efeb538ff710641e0f733fe6f79a4d60.pdf","sourceUrl":null},"ai":{"faq":[{"question":"What are the specifications of the LM34904?","answer":"It is a single-channel high-side N-channel power switch with 500 mA maximum output, 400 mOhm typical on-resistance, operating from 2.8 V to 5.3 V load voltage.
