L6226 DMOS dual full bridge driver Datasheet - production data Undervoltage lockout Integrated fast free wheeling diodes Applications 62 3 3RZH6U 2 Bipolar stepper motor Dual or quad DC motor Features Description Operating supply voltage from 8 to 52 V 2.8 A output peak current (1.4 A DC) The L6226 is a DMOS dual full bridge designed for motor control applications, realized in R 0.73 typ. value at T = 25 C DS(on) J multipower-BCD technology, which combines Operating frequency up to 100 kHz isolated DMOS power transistors with CMOS and Programmable high side overcurrent detection bipolar circuits on the same chip. Available in and protection PowerSO36 and SO24 (20+2+2) packages, the L6226 features thermal shutdown and a non- Diagnostic output dissipative overcurrent detection on the high side Paralleled operation power MOSFETs plus a diagnostic output that Cross conduction protection can be easily used to implement the overcurrent protection.
