It integrates a serial interface for control and a status flag output that asserts during over-current or over-temperature fault conditions. ## 97 mOhm on-resistance and 1 A per channel Each of the four outputs is rated for 1 A continuous with a typical on-resistance of 97 mOhm. The 3:4 input-to-output ratio implies an internal charge pump generates the gate drive for the fourth output from the available load rail. It is no longer in production from Texas Instruments. Sourcing is limited to independent distribution and surplus inventory.","metaTitle":"TI TPS2228PWP PCMCIA Power Switch, 4-Ch, 97mOhm, Obsolete","metaDescription":"Texas Instruments TPS2228PWP PCMCIA switch IC, 4 high-side outputs at 1A, 97mOhm Rds(on), serial interface, status flag, -40 to 85°C.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"Obsolete","categoryPath":["Power Management (PMIC / Gate Driver)"],"specifications":{"Mfr":"Texas Instruments","Series":"-","Package":"Tube","Features":"Status Flag","Interface":"Serial","Input Type":"-","Output Type":"-","Switch Type":"PCMCIA Switch","Rds On (Typ)":"97mOhm","Mounting Type":"Surface Mount","Package / Case":"20-PowerTSSOP (0.173\\\", 4.40mm Width)","Product Status":"Obsolete","Voltage - Load":"1.8V, 3.3V, 5V","lifecycle_stage":"eol_hot","Fault Protection":"Current Limiting (Fixed), Over Temperature","Number of Outputs":"4","Base Product Number":"TPS2228","Output Configuration":"High Side","Ratio - Input:Output":"3:4","Operating Temperature":"-40°C~85°C(TA)","Current - Output (Max)":"1A","Supplier Device Package":"20-HTSSOP","Voltage - Supply (Vcc/Vdd)":"Not Required"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$4.6500","priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/2d1bf787b22990ea5130c7cee83648d9.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/TPS2228PWP/alternatives.json"},"ai":{"faq":[{"question":"Where can I buy the TPS2228PWP and get a price?","answer":"The TPS2228PWP is obsolete and no longer in production.
