WT51FM24
WT51FM24 is an 8-bit BLDC motor controller series product. It uses an 8-bit 8052 core with an operating frequency of up to 24MHz, a Flash memory of up to 16K bytes, an SRAM of up to 512 bytes, and a wealth of peripherals and interfaces. WT51FM24 can operate in 12V sensor-less BLDC motor applications and has built-in 12V to 5V LDO, BEMF detection circuit and 26V NN structure gate driver. The green package uses QFN24, which is suitable for single-phase/three-phase BLDC motor systems.
