The device operates within a supply voltage range of 2.7 V to 3.6 V, with a maximum operating temperature of +85 °C and a minimum of -20 °C. It utilizes a VFBGA package with 33 terminals and measures 2.5 mm in length. The typical operating supply current is 4 mA.

Feature Summary

• Integrates a half-bridge driver with a dedicated CMOS LDO regulator for stable operation.

Applications

• Fan control systems
• Motor motion control applications
• Ignition driver circuits

Procurement Notes

Verify the Not Recommended for New Designs (NRND) status before procurement. Confirm availability through authorized distributors as standard stock may be limited. Ensure the VFBGA package specifications align with existing PCB footprints. Validate that the 2.7 V to 3.6 V supply range meets system requirements. Check RoHS compliance documentation for regulatory adherence.

Selection Notes

Select this component for single-channel half-bridge applications requiring low power consumption. The integrated LDO simplifies power management by reducing external component count. Consider the 500 mA output capability for driving small motors or coils. Evaluate the -20 °C to +85 °C temperature range against environmental conditions. Assess the VFBGA package size constraints during layout design.
