The half-bridge configuration (two outputs, high-side and low-side) lets you create a push-pull or full-bridge topology with a single IC. ## Protection and temperature range Fault protection includes ESD, over-temperature shutdown, and undervoltage lockout (UVLO). The over-temperature protection is a hard thermal shutdown — if the junction hits the limit, the driver shuts down until it cools. That's useful in a transformer-drive scenario where a shorted secondary or overloaded output could otherwise cook the part. The UVLO ensures the driver doesn't try to switch with a supply voltage too low to fully enhance the external MOSFETs, which would put them in the linear region and burn power. Operating junction temperature spans -40°C to 150°C. ## Sourcing and lifecycle The MAX256ASA+ carries an Active lifecycle status with ROHS3 compliance.","metaTitle":"MAX256ASA+ Half-Bridge Driver, 1A, 8-SOIC-EP, Active","metaDescription":"Maxim MAX256ASA+ half-bridge MOSFET driver, 1A per channel, 3V-5.5V supply, internal oscillator and watchdog, -40°C to 150°C.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":"ROHS3 Compliant","productStatus":"Active","categoryPath":["Analog & Data Acquisition"],"specifications":{"Package":"Tube","Features":"Internal Oscillator, Watchdog Timer","Interface":"Logic","Load Type":"Inductive","Technology":"Power MOSFET","Applications":"Transformers","Rds On (Typ)":"500mOhm LS + HS","Mounting Type":"Surface Mount","Package / Case":"8-SOIC (0.154\\\", 3.90mm Width) Exposed Pad","Voltage - Load":"3V ~ 5.5V","lifecycle_stage":"eol_hot","Fault Protection":"ESD, Over Temperature, UVLO","Voltage - Supply":"3V ~ 5.5V","Output Configuration":"Half Bridge (2)","Operating Temperature":"-40°C ~ 150°C (TJ)","Supplier Device Package":"8-SOIC-EP","Current - Output / Channel":"1A"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$10.74","stockQuantity":0,"priceTiers":[{"qty":1,"price":"$10.74000","currency":"USD"},{"qty":10,"price":"$9.70700","currency":"USD"},{"qty":25,"price":"$9.25520","currency":"USD"},{"qty":100,"price":"$8.03620","currency":"USD"},{"qty":250,"price":"$7.67500","currency":"USD"},{"qty":500,"price":"$6.99778","currency":"USD"},{"qty":1000,"price":"$6.09484","currency":"USD"}]},"links":{"datasheetUrl":"https://datasheets.maximintegrated.com/en/ds/MAX256.pdf","sourceUrl":null},"ai":{"faq":[{"question":"Does MAX256ASA+ have over-temperature protection?","answer":"Yes, the MAX256ASA+ includes over-temperature shutdown as part of its fault protection set, along with ESD and undervoltage lockout (UVLO).
