It uses an SPI interface to program the eight outputs individually. Each N-channel output sinks up to 70 mA with a typical on-resistance of 2 Ohms, in a 20-TSSOP exposed-pad package. The load supply range is 2.3 V to 5.5 V. ## Temperature grade and environment Rated for junction temperatures from -40°C to 150°C, the MAX4820EUP+ suits under-hood automotive, industrial oven controls, and outdoor telecom enclosures where ambient heat exceeds typical commercial limits. The 150°C junction ceiling gives headroom for self-heating from simultaneous channel activation in a confined board space. ## Sourcing and lifecycle The MAX4820EUP+ carries an Active product status and is ROHS3 compliant.","metaTitle":"MAX4820EUP+ SPI Relay Driver, 8-Channel Low-Side, 70mA","metaDescription":"MAX4820EUP+ 8-channel low-side relay/solenoid driver with SPI interface, 2 Ohm Rds(on), -40 to 150°C, active production.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":"ROHS3 Compliant","productStatus":"Active","categoryPath":["DC-DC Power Modules"],"specifications":{"Package":"Tube","Interface":"SPI","Output Type":"N-Channel","Switch Type":"Relay, Solenoid Driver","Rds On (Typ)":"2Ohm","Mounting Type":"Surface Mount","Package / Case":"20-TSSOP (0.173\\\", 4.40mm Width) Exposed Pad","Voltage - Load":"2.3V ~ 5.5V","lifecycle_stage":"eol_hot","Number of Outputs":"8","Output Configuration":"Low Side","Ratio - Input:Output":"1:8","Operating Temperature":"-40°C ~ 150°C (TJ)","Current - Output (Max)":"70mA","Supplier Device Package":"20-TSSOP-EP"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$5.84","stockQuantity":0,"priceTiers":[{"qty":1,"price":"$5.84000","currency":"USD"},{"qty":10,"price":"$5.24800","currency":"USD"},{"qty":25,"price":"$4.96160","currency":"USD"},{"qty":100,"price":"$4.30020","currency":"USD"},{"qty":250,"price":"$4.07972","currency":"USD"},{"qty":500,"price":"$3.66070","currency":"USD"},{"qty":1000,"price":"$3.08734","currency":"USD"},{"qty":2500,"price":"$2.93298","currency":"USD"}]},"links":{"datasheetUrl":"https://datasheets.maximintegrated.com/en/ds/MAX4820-MAX4821.pdf","sourceUrl":null},"ai":{"faq":[{"question":"What is the difference between MAX4820EUP+ and MAX4820EUP+T?","answer":"The suffix indicates the shipping medium: the MAX4820EUP+ ships in a tube, while the MAX4820EUP+T variant ships in tape-and-reel.
