L6227Q, Привод двигателя, двойной, 8В до 52В питание, 52В/1.4А/2 выхода, VFQFPN-32

The L6227Q is a dual DMOS full-bridge Driver with PWM current controller. It is realized in BCD technology, which combines isolated DMOS power transistors with CMOS and bipolar circuits on the same chip. The device also includes two independent constant off time PWM current controllers that performs the chopping regulation. It features a non-dissipative overcurrent protection on the high-side power MOSFETs and thermal shutdown.

• Non-dissipative overcurrent protection
• Dual independent constant tOFF PWM current controllers
• Slow decay synchronous rectification
• Cross conduction protection
• Thermal shutdown
• Under-voltage lockout
• Integrated fast free-wheeling diodes
• 2.8A Output peak current (1.4A DC)
• 0.73R at Tj=25°C Typical RDS(ON)
• Up to 100kHz operating frequency
