LC898302AXA-MH

Overview

The LC898302AXA-MH is a linear vibrator driver manufactured by onsemi, designed for haptic feedback applications. It operates within a supply voltage range of 2.7 V to 4.5 V and delivers an output current of 200 mA. The device features a half-bridge topology with two outputs and functions at a working frequency of 50 kHz. It maintains a low operating supply current of 1 uA and provides output voltages of 2.8 V and 2.9 V. The component supports surface mount installation in a WLCSP-6 package and operates reliably across a temperature range of -30°C to +85°C.

Feature Summary

• Linear vibrator driver optimized for haptic feedback systems
• Half-bridge topology providing dual independent outputs
• Ultra-low quiescent current consumption for power efficiency
• Compact WLCSP-6 surface-mount packaging

Applications

• Mobile device haptic feedback modules
• Wearable technology vibration actuators
• Handheld gaming controller rumble motors

Procurement Notes

This component is officially designated as End-of-Life (EOL) by the manufacturer. Production has ceased, and the part is subject to discontinuance notifications. Availability is restricted to remaining stock or secondary market channels. Verify specific lot dates and authenticity through authorized distributors before procurement. Designers should initiate replacement strategies immediately due to limited future supply.

Selection Notes

Select this driver when a compact solution for linear resonant actuators is required in space-constrained portable electronics. The WLCSP-6 footprint minimizes board area usage compared to traditional packages. Ensure the application voltage remains within the 2.7 V to 4.5 V window. Consider thermal management requirements given the 200 mA output capability and the small package size during continuous operation.

Part Context

Part of the LC898302AXA series from onsemi, focusing on low-power motor and motion control. This series targets consumer electronics requiring precise haptic responses. The LC898302 variant specifically addresses dual-output needs for complex vibration patterns. It belongs to the broader PMIC category, integrating power management with signal driving capabilities for efficient system design.

Replacement Considerations

No public confirmed substitute part numbers are available in the provided documentation. Due to the EOL status, engineers must evaluate alternative drivers based on pin compatibility and electrical specifications. Cross-reference with other haptic driver families from different manufacturers if form-fit-function replacement is necessary.
