It outputs a PWM signal to drive external half-bridge MOSFETs — this is a pre-driver, not a fully integrated power stage, so your BOM needs the FET pair and a bootstrap diode per phase. The 200 mA gate drive current is sized for small-signal MOSFETs typical in 12V fan applications; if you are switching larger dies or need faster rise times, budget a separate gate driver. ## 14-SSOPB footprint and temperature grade Housed in a 14-TSSOP (4.40 mm wide) package with the supplier device code 14-SSOPB — the same 0.65 mm pitch as the standard TSSOP-14 footprint, so no layout surprise if you have used that land pattern before. Surface-mount only; no through-hole variant exists. ## DMOS output stage and PWM interface The DMOS output technology delivers the 200 mA gate drive with the low Rds(on) characteristic of vertical DMOS transistors — this keeps the driver's own dissipation low in the 14-pin package. The PWM input accepts a standard logic-level signal for speed control; the controller handles commutation and direction internally. No external Hall sensors are mentioned in the function block — confirm whether your motor uses sensorless back-EMF commutation or if you need a sensor input elsewhere. For a production BOM targeting 12V BLDC fan drivers, this part is safe to qualify in now without an imminent obsolescence watch.","metaTitle":"ROHM BD61243FV-GE2 BLDC Motor Driver, 5.5V-16V, 14-SSOPB","metaDescription":"ROHM BD61243FV-GE2 BLDC motor pre-driver, 5.5V-16V supply, 200mA gate drive, PWM interface, -40°C to 105°C.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":"ROHS3 Compliant","productStatus":"Active","categoryPath":["Discrete Semiconductors"],"specifications":{"Package":"Tape & Reel (TR); Cut Tape (CT)","Function":"Controller - Commutation, Direction Management","Interface":"PWM","Technology":"DMOS","Applications":"Fan Motor Driver","Mounting Type":"Surface Mount","Package / Case":"14-TSSOP (0.173\\\", 4.40mm Width)","lifecycle_stage":"eol_hot","Current - Output":"200mA","Voltage - Supply":"5.5V ~ 16V","Motor Type - AC, DC":"Brushless DC (BLDC)","Output Configuration":"Pre-Driver - Half Bridge (2)","Operating Temperature":"-40°C ~ 105°C (TA)","Supplier Device Package":"14-SSOPB"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$1.42","stockQuantity":0,"priceTiers":[{"qty":1,"price":"$1.42000","currency":"USD"},{"qty":10,"price":"$1.27000","currency":"USD"},{"qty":25,"price":"$1.20520","currency":"USD"},{"qty":100,"price":"$0.98980","currency":"USD"},{"qty":250,"price":"$0.92528","currency":"USD"},{"qty":500,"price":"$0.81768","currency":"USD"},{"qty":1000,"price":"$0.64554","currency":"USD"},{"qty":2500,"price":"$0.60900","currency":"USD"}]},"links":{"datasheetUrl":"https://cdn.icboms.com/d6154e264170f6850f5f68db633f12a3.pdf","sourceUrl":null},"ai":{"faq":[{"question":"Can BD61243FV-GE2 be used for 12V fan motor applications?","answer":"Yes.
