TB6575FNG
TB6575FNG is PWM Sensorless Controller manufactured by Toshiba.
TOSHIBA CMOS Integrated Circuit Silicon Monolithic
PWM Sensorless Controller for 3-Phase Full-Wave BLDC Motors
1. Description
The TB6575FNG provides sensorless mutation and PWM current control for 3-phase full-wave BLDC motors. It controls rotation speed by changing a PWM duty cycle by analog voltage.
2. Features
Weight: 0.14 g (Typ.)
- 3-phase full-wave sensorless drive
- PWM chopper drive
- PWM duty cycle control by analog input
- 20-m A current sink capability on PWM output pins
- Overcurrent protection
- Forward/reverse rotation
- Lead angle control (7.5 ° and 15 °)
- Overlap mutation
- Rotation speed sensing signal
- DC excitation mode to improve startup characteristic
- DC excitation time and forced mutation time for startup operation can be changed.
- Forced mutation frequency can be selected. (f XT/(6 × 216), f XT/(6 × 217), f XT/(6 × 218) )
- Output polarity switching (P-channel + N-channel, N-channel + N-channel)
