L6207Q DMOS dual full bridge driver Datasheet - production data Description The L6207Q device is a DMOS dual full bridge driver designed for motor control applications, realized in BCDmultipower 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 perform the chopping regulation. Available in PP a VFQFPN48 7 x 7 package, the L6207Q device features thermal shutdown and a non-dissipative overcurrent detection on the high-side Power MOSFETs. Features Operating supply voltage from 8 to 52 V 5.6 A output peak current R 0.3 typ. value at T = 25 C DS(on) j Operating frequency up to 100 kHz Non-dissipative overcurrent protection Dual independent constant t PWM current OFF controllers Slow decay synchronous rectification Cross conduction protection Thermal shutdown Undervoltage lockout Integrated fast freewheeling diodes Applications Bipolar stepper motor Dual or quad DC motor June 2013 DocID018993 Rev 3 1/27 This is information on a product in full production. www.st.com 9)4)31 Contents L6207Q Contents 1 Block diagram 3 2 Electrical data 4 2.1 Absolute maximum ratings . 4 2.2 Recommended operating conditions . 4 3 Pin connection 5 4 Electrical characteristics . 7 5 Circuit description 10 5.1 Power stages and charge pump 10 5.2 Logic inputs 11 5.3 PWM current control . 12 5.4 Slow decay mode . 15 5.5 Non-dissipative overcurrent detection and protection . 16 5.6 Thermal protection 18 6 Application information . 19 7 Output current capability and IC power dissipation 21 8 Thermal management . 22 9 Electrical characteristics curves 23 10 Package information 24 11 Order codes . 26 12 Revision history . 26 2/27 DocID018993 Rev 3
