The L6227Q is a DMOS dual full-bridge designed for motor control applications, realized in BCD multipower technology.
The L6227Q features thermal shutdown and a non-dissipative overcurrent protection on the high-side power MOSFETs plus a diagnostic output that can be easily used to implement the overcurrent protection.
The device also includes two independent constant off-time PWM current controllers which perform the chopping regulation.
- Operating supply voltage from 8 to 52 V

- Operating frequency up to 100 kHz
- Non dissipative overcurrent protection
- Dual independent constant tOFF PWM current controllers
- Slow decay synchronous rectification
- Cross conduction protection
- Thermal shutdown
- Undervoltage lockout
- Integrated fast free wheeling diodes
