Overview
The LB11852FV-MPB-H is a fan motor driver manufactured by onsemi, designed for driving small fan motors requiring speed control. It operates within a supply voltage range of 5.5 V to 16 V and draws a typical operating supply current of 15 mA. The device supports SMD/SMT installation in a 20-SSOP-J package and functions reliably across an operating temperature range of -30°C to +95°C. Maximum power dissipation is rated at 800 mW. This component belongs to the LB11852FV series and is classified under Motor / Motion / Ignition Controllers & Drivers.
Feature Summary
- Designed specifically for driving small fan motors with integrated speed control capabilities
- Supports full-wave drive operation for efficient motor management
- Utilizes a compact SSOP-J-20 surface-mount package suitable for space-constrained designs
Applications
- Small fan motor speed control systems
- Consumer electronics cooling solutions
- Industrial equipment ventilation control
Procurement Notes
Verify end-of-life status and availability through authorized distributors. Confirm RoHS compliance details and moisture sensitivity level prior to procurement. Ensure packaging format matches production requirements. Check for obsolescence notices or lifecycle changes from onsemi before finalizing design-in decisions.
Selection Notes
Select this component when designing circuits for small fan motor applications requiring PWM or parallel control. Consider the 5.5 V to 16 V input range and 15 mA supply current for power budgeting. The SSOP-J-20 package dictates PCB layout constraints. Verify thermal performance against the 800 mW dissipation limit in the intended enclosure environment.
Part Context
This part belongs to the LB11852FV series from onsemi, categorized under PMIC - Power Management ICs and Motor Drivers. It is distinct from other series like LV8702V, which targets stepping motors. The MPB-H suffix indicates specific packaging and handling characteristics within the broader product family.
Replacement Considerations
Publicly confirmed substitute part numbers are not available in the provided documentation. Designers should consult onsemi directly for recommended alternatives or cross-reference options based on pin compatibility and electrical specifications.
