2-phase DMOS full-bridge driver, 8-52 V, 2x 1.4 A, Power-SO36

The L6226 is a DMOS dual full bridge for motor control applications, realised in multipower BCD technology, which combines isolated DMOS power transistors with CMOS and bipolar circuits on the same chip. Available in PowerDIP24 (20+2+2), PowerSO36 and SO24 (20+2+2) enclosures, the L6226 features a thermal shut-off function, non-dissipative over-current detection on high-power MOSFETs and a diagnostic output.

• 2.8 A peak output current (1.4 A DC)

• Operating frequency up to 100 kHz
• Programmable load-side overcurrent protection
• Diagnostic output
• Parallel operation
• Cross-conductor protection
• Thermal shutdown
• Undervoltage lock
• Integrated high-frequency free-wheeling diodes

Typical application:

• Bipolar stepper motors
