The paper addresses the problem of inductive load drivers for automotive applications. The design integrates single-chip in a 0.35 μm low-cost HVMOS technology both the digital circuitry for control and communication with SPI/CAN vehicle networks and the multi-channel drivers optimized for inductive loads. To face ISO26262 requirements also a diagnostic block is embedded. As proved by experimental measurements on fabricated test-chip each channel can sustain up to 650 mA DC current, 1.1 A pulsed current with clamped energy up to 100 mJ, being compliant with automotive harsh operating conditions of ESD up to 4 kV and temperature range from −40 to 150 °C.
