Overview
The NCP5901BEMNTBG is a half-bridge MOSFET gate driver designed for synchronous buck applications. It operates within a supply voltage range of 4.5 V to 13.2 V and supports high-side bootstrap voltages up to 35 V. The device features non-inverting inputs with logic thresholds of 1 V and 2 V. Typical switching performance includes rise and fall times of 16 ns and 11 ns, respectively. Propagation delays are capped at 30 ns for both turn-on and turn-off states. It functions in an extended temperature range from 0°C to 150°C junction temperature.
Feature Summary
- Integrated high-side and low-side drivers optimized for synchronous buck converter topologies
- Non-inverting input configuration simplifies control interface requirements
- Robust output stage capable of driving N-channel MOSFETs with high peak current
Applications
- Synchronous buck power supplies
- Point-of-load (POL) converters
- DC-DC step-down regulator circuits
Procurement Notes
Verify component status as the NCP5901BEMNTBG is classified as obsolete or end-of-life by onsemi. Confirm availability through authorized distributors or check for valid substitute part numbers before finalizing procurement plans. Ensure all ordering suffixes match the required package and tape specifications.
Selection Notes
Select this component for designs requiring a dedicated half-bridge driver with fast switching speeds and high voltage tolerance. Consider the 8-DFN package constraints and thermal dissipation requirements. Verify that the input logic levels align with the controller MCU or PWM signal source capabilities.
Part Context
This part belongs to the NCP5901 series of compatible synchronous buck MOSFET drivers manufactured by onsemi. It is specifically engineered to provide efficient gate drive signals for power stages in DC-DC conversion systems, ensuring reliable operation under varying load conditions.
Replacement Considerations
Check for direct substitutes such as NCP5901MNTBG or NCP5901BDR2G if available, though pinout and package compatibility must be verified. Consult official obsolescence notices for recommended replacement strategies.
