• Ignition driver applications

Procurement Notes

Verify the specific ordering suffix and package variant against the official STMicroelectronics datasheet before procurement. Confirm that the intended application environment remains within the specified 0°C to +70°C operating temperature range. Ensure the supply voltage does not exceed the maximum rating of 36 V to prevent device damage. Check for humidity sensitivity handling requirements during storage and assembly.

Selection Notes

Select this component when a design requires multiple independent half-bridge outputs in a single package. It is suitable for applications needing 3 A output current capability with a supply voltage up to 36 V. Consider its suitability for both audio amplification and general motor or ignition driving tasks. Verify that the thermal management strategy supports the device's power dissipation characteristics within the stated operating temperature limits.
