L6226

L6226 DMOS dual full bridge driver Datasheet - production data  Undervoltage lockout  Integrated fast free wheeling diodes 3 3RZHU62 62 Features  Operating supply voltage from 8 to 52 V  2.8 A output peak current (1.4 A DC)  RDS(on) 0.73  typ. value at TJ = 25 °C  Operating frequency up to 100 kHz  Programmable high side overcurrent detection and protection  Diagnostic output  Paralleled operation  Cross conduction protection  Thermal shutdown Applications  Bipolar stepper motor  Dual or quad DC motor Description The L6226 is a DMOS dual full bridge designed for motor control applications, realized in multipower-BCD technology, which combines isolated DMOS power transistors with CMOS and bipolar circuits on the same chip. Available in PowerSO36 and SO24 (20+2+2) packages, the L6226 features thermal shutdown and a nondissipative overcurrent detection on the high side power MOSFETs plus a diagnostic output that can be easily used to implement the overcurrent protection.
