Overview
The LTC1154HS8#TRPBF is a high-side N-channel MOSFET gate driver manufactured by Analog Devices Inc. It operates within an input voltage range of 3V to 20V and supports output currents up to 1A for both sourcing and sinking. The device features a fixed 150ns propagation delay and is housed in an 8-lead SOIC package.
Feature Summary
- Provides robust high-side drive capability for N-channel power MOSFETs
- Features fast switching performance with low propagation delay
- Includes integrated bootstrap diode for simplified circuit design
Applications
- High-side switching in DC-DC converter topologies
- Motor control bridge circuits requiring isolated or floating gate drive
- Power supply stages utilizing synchronous rectification
Procurement Notes
Verify the specific HS8 suffix against the official Analog Devices datasheet to confirm pinout compatibility and thermal characteristics. Confirm RoHS compliance status through current manufacturer documentation, as packaging revisions may affect material declarations. Ensure the component matches the required operating temperature range for your specific application environment before finalizing procurement.
Selection Notes
Select this component when a dedicated high-side driver is required for N-channel MOSFETs in compact designs. It eliminates the need for external bootstrap components due to the integrated diode. Consider the 1A peak drive current and 150ns delay for applications demanding moderate switching speeds without complex level-shifting logic.
Part Context
This part belongs to the LTC1154 family of single high-side MOSFET drivers. It is designed to simplify the interface between low-voltage control logic and high-side power switches. The series offers a balance of performance and simplicity for various power management applications.
Replacement Considerations
Consult the official Analog Devices cross-reference guide for verified substitutes. Generic replacements may differ in drive strength, propagation delay, or internal bootstrap configuration.
