LV88551JA-AH

Overview

The LV88551JA-AH is a single-phase brushless DC motor controller manufactured by onsemi. It operates within a supply voltage range of 6 V to 20 V, with a maximum operating voltage of 16 V. The device features a typical switching frequency of 48 kHz and delivers a maximum output current of 50 mA. It is housed in a compact SSOP-20 package measuring 5.65 x 4.4 x 1.4 mm. The component supports an extended temperature range from -40 °C to +150 °C.

Feature Summary

• Single-phase full-wave output configuration for BLDC motor control
• Integrated driver capable of delivering up to 50 mA output current
• Designed for surface-mount installation in space-constrained applications

Applications

• Small fan speed control systems
• Precision actuator positioning
• HVAC blower motor regulation

Procurement Notes

Verify end-of-life status and availability through authorized distributors. Confirm moisture sensitivity level and reflow soldering profiles prior to assembly. Ensure compliance with RoHS directives and check for specific automotive qualification requirements if applicable to the target environment.

Selection Notes

Select this component for single-phase BLDC applications requiring low current drive. Compare against LV8856x series for multi-phase needs. Verify thermal dissipation capabilities given the small SSOP package size and high maximum junction temperature rating.

Part Context

Part of the LV88551/54 family of non-autonomous BLDC motor drivers. Designed for consumer electronics and industrial automation where cost-effective, compact motor control solutions are required. Complements onsemi's broader power management portfolio.

Replacement Considerations

Check for direct pin-compatible alternatives within the LV885xx series. Verify electrical parameter compatibility before substituting with other single-phase controllers.
