LB11988-A-E

Overview

The LB11988-A-E is a fan motor controller and driver manufactured by onsemi. It is designed for brushless DC fan applications, operating within a supply voltage range of 5 V to 22 V. The device features a low operating supply current of 24 mA and supports surface mount installation in an SSOP-24 package. It dissipates up to 500 mW of power and functions reliably across a temperature range from -30°C to +75°C.

Feature Summary

Integrated control and drive circuitry for brushless fan motors
Low power consumption with minimal operating supply current
Robust thermal performance suitable for compact designs

Applications

Computer cooling fans
Server chassis ventilation systems
Consumer electronics cooling modules

Procurement Notes

Verify component authenticity through authorized distribution channels. Confirm the specific suffix matches the required operational specifications. Check for end-of-life status or discontinuation notices prior to finalizing design-in decisions. Ensure storage conditions comply with moisture sensitivity level requirements during handling.

Selection Notes

Evaluate the 5 V to 22 V input voltage compatibility against system power rails. Assess the 500 mW power dissipation capability relative to the thermal environment. Consider the SSOP-24 footprint constraints for PCB layout. Verify that the operating temperature range meets the environmental demands of the target application.

Part Context

This component belongs to the LB11988V series of fan motor drivers. It provides a specialized solution for managing brushless DC fans in space-constrained electronic devices. The series focuses on efficient motor control with integrated protection features.
