LB11988HR-TLM-E

Overview

The LB11988HR-TLM-E is a brushless DC motor driver manufactured by onsemi. It operates within an output block power supply range of 5 V to 22 V and features a maximum power dissipation of 500 mW. The device functions across a temperature range from -30 °C to +75 °C and utilizes a 24-pin LSSOP package with SMD/SMT mounting style. It is classified under Motor / Motion / Ignition Controllers & Drivers.

Feature Summary

• Integrated control circuitry for brushless DC motors
• Supports surface mount installation in compact designs

Applications

• Fan motor control systems
• Automotive body electronics
• Industrial motion control applications

Procurement Notes

Verify the specific suffix HR against official datasheets, as public records primarily reference the LB11988V variant. Confirm current availability status as the LB11988 series has been subject to discontinuance notifications. Ensure compliance with RoHS directives and moisture sensitivity levels before integration into production schedules.

Selection Notes

Select this component for low-power brushless motor applications requiring a 24-pin form factor. Evaluate thermal management requirements given the 500 mW power dissipation limit. Compare against the LB11988V variant if pinout or specific electrical characteristics differ significantly for the target design constraints.

Part Context

This part belongs to the LB11988 family of fan and motor controllers produced by onsemi. The series is categorized under PMIC and Motor Control product lines. The manufacturer integrates these drivers into broader automotive and industrial solution portfolios, often replacing legacy Hitachi Semiconductor components following corporate acquisitions.

Replacement Considerations

Public documentation indicates the LB11988 series is End-of-Life (EOL). Verify if the LB11988V-TLM-E serves as a direct functional substitute or if alternative motor drivers from the current portfolio are required.
