L6229 is a DMOS fully integrated three-phase motor driver with overcurrent protection. Realized in MultiPower-BCD technology, the device combines isolated DMOS power transistors with CMOS and bipolar circuits on the same chip. The device includes all the circuitry needed to drive a three-phase BLDC motor including: a three-phase DMOS bridge, a constant off time PWM current controller, and the decoding logic for single-ended hall sensors that generates the required sequence for the power stage. The L6229 features an operating supply voltage range from 8 to 52V, a 2.8A output peak current (1.4A DC), a typical RDS(ON) value of 0.73Ω at 25°C, an operating frequency up to 100KHz, and other characteristics.
The L6229 is a fully integrated DMOS driver for three-phase brushless DC (BLDC) motors, realized in MultiPower-BCD technology. It combines isolated DMOS power transistors with CMOS and bipolar circuits on a single chip to drive the motor and decode single-ended Hall sensors.
