LV8824QA: PWM Pre-Drive Three-Phase Brushless Motor Driver
The LV8824QA is a PWM pre-driver IC suitable for use in 3-phase brushless motors. This IC was designed based on the assumption that Nch FETs are used as the upper and lower output transistors. The rotational speed is controllable by inputting PWM pulse or DC voltage externally and changing duty. LV8824QA incorporates latch-type constraint protection circuit.
Features- IO max = 50mA
- Speed control and synchronous rectification by PWM direct input (3.3V input-ready) and DC voltage.
- 3-Hall FG output
- Latch type constraint protection circuit (latch is released by S/B and F/R.)
- Forward/reverse switch circuit, Hall bias pin
- Power saving circuit
- Current limiter circuit, Low-voltage protection circuit, Thermal shut-down circuit
- Charge pump circuit (external Nch/Nch), 5V regulator output.
- Start/Brake circuit
