Rated for 800 mA output current, it drives external NMOS and PMOS FETs in the power stage, with a load voltage range of 8 V to 40 V and a supply voltage range of 6 V to 58 V. ## SPI control and current management The SPI interface handles configuration and diagnostics — the controller adjusts gate drive timing, dead-time, and fault reporting over the serial bus, which reduces the number of discrete control lines needed between the MCU and the pre-driver. Functionally it is a Controller - Current Management device, meaning it regulates the current delivered to the motor windings through the external FET bridge, not just switching them on and off.","metaTitle":"NXP MC33937APEK574 BLDC Pre-Driver, 800mA, 54-SSOP","metaDescription":"NXP MC33937APEK574 automotive BLDC motor pre-driver, 3-phase half-bridge, SPI, 800mA output, 8-40V load, active production.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":"Not applicable","productStatus":"Active","categoryPath":["Discrete Semiconductors"],"specifications":{"Package":"Bulk","Function":"Controller - Current Management","Interface":"SPI","Technology":"NMOS, PMOS","Applications":"Automotive","Mounting Type":"Surface Mount","Package / Case":"54-SSOP (0.295\\\", 7.50mm Width) Exposed Pad","Voltage - Load":"8V ~ 40V","lifecycle_stage":"eol_hot","Current - Output":"800mA","Voltage - Supply":"6V ~ 58V","Motor Type - AC, DC":"Brushless DC (BLDC)","Motor Type - Stepper":"Multiphase","Output Configuration":"Pre-Driver - Half Bridge (3)","Operating Temperature":"-40°C ~ 150°C (TJ)","Supplier Device Package":"54-SOIC-EP"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$10.16","stockQuantity":0,"priceTiers":[{"qty":30,"price":"$10.16000","currency":"USD"}]},"links":{"datasheetUrl":"https://cdn.icboms.com/676cdc19ddfd1e21201e2bcc7918c52f.pdf","sourceUrl":null},"ai":{"faq":[{"question":"Will MC33937APEK574 drop into a board designed for MC33937APEK without rewiring?","answer":"The MC33937APEK574 shares the same base part number and package (54-SSOP exposed pad) as the MC33937APEK variant — functionally identical for the same 3-phase BLDC pre-driver role.
