BLDC fan controller with six half-bridge outputs
The BD62018AFS-E2: The BD62018AFS- from ROHM Semiconductor is a controller for brushless DC (BLDC) motors, handling commutation and direction management through a parallel interface. Its six half-bridge outputs drive the three phases of a BLDC motor, with a 5 V load rail and a supply range of 10 V to 18 V. The part is explicitly listed for fan controller applications, making it a targeted choice for thermal management in power supplies, servers, or industrial enclosures.
Package, temperature range, and rework notes
Pin 1 is clearly marked on the SOP body; the 0.65 mm typical lead pitch is forgiving under a hot-air station if a rework is needed — just preheat the board to 100°C before lifting to keep the pads intact.
