Overview
The LB11961-MPB-H is a single-phase full-wave driver for fan motors manufactured by onsemi. It integrates 16V, 1.0A output transistors and built-in regeneration diodes to minimize external components. The device features an internal thermistor input for variable speed control functionality. It operates with a supply voltage range of 4.5V to 16V and supports an operating temperature range from -30°C to 90°C (TA). The component is housed in a 14-pin HSSOP surface-mount package.
Feature Summary
- Single-phase full-wave driving capability with integrated output transistors
- Built-in regeneration diodes reduce the requirement for external components
- Internal thermistor input enables variable speed control functions
Applications
- Fan motor drivers
- Appliance cooling systems
- HVAC unit ventilation controls
Procurement Notes
Verify the specific suffix MPB-H against official onsemi documentation to confirm pinout and packaging details. Ensure compatibility with system voltage requirements within the 4.5V to 16V range. Confirm thermal management strategies align with the specified operating temperature limits. Cross-reference part numbers with authorized distributors to avoid counterfeit components.
Selection Notes
Select this component for applications requiring simple single-phase AC or brushed DC motor control with minimal external circuitry. The integrated regeneration diodes simplify design compared to discrete solutions. Consider the thermistor input feature if variable speed operation based on temperature is required. Verify that the HSSOP package fits the available PCB space constraints.
Part Context
This part belongs to onsemi's motor driver portfolio, specifically designed for low-power fan applications. It utilizes bipolar technology to provide robust switching capabilities. The integration of control logic and power stages into a single package reduces board space and assembly complexity for consumer electronics and industrial ventilation systems.
Replacement Considerations
Consult official onsemi substitution guides for verified alternatives. Generic replacements may lack the integrated regeneration diodes or thermistor interface. Verify electrical parameters such as supply voltage and current ratings before considering any cross-reference.
