Overview
The NCP5901BMNTBG is a half-bridge MOSFET gate driver manufactured by onsemi, designed for VR12 applications. It operates within a supply voltage range of 4.5 V to 13.2 V and supports a maximum high-side bootstrap voltage of 35 V. The device features two drivers with non-inverting inputs, delivering typical rise and fall times of 16 ns and 11 ns, respectively. Turn-on and turn-off propagation delays are limited to 30 ns each. It functions reliably across an operating temperature range from -10°C to +125°C.
Feature Summary
- Integrated half-bridge topology optimized for synchronous rectification in power conversion circuits.
- Capable of driving N-channel MOSFETs with high-side voltages up to 35 V via bootstrap configuration.
- Provides fast switching performance with low propagation delay and matched timing characteristics.
Applications
- VR12 load line modulation (LLM) controller interfaces
- Synchronous buck converter gate drive stages
- High-efficiency DC-DC power supply designs
Procurement Notes
Verify the specific ordering suffix 'BMNTBG' corresponds to the 8-DFN package and tape-and-reel container format. Confirm RoHS compliance status and REACH declaration requirements for your region. Check for any recent Product Change Notifications regarding wafer fab or packaging material updates that may affect long-term availability or assembly parameters.
Selection Notes
Select this component when a compact half-bridge driver is required for VR12 or similar synchronous rectification topologies. Ensure the input logic voltage levels align with the specified 1V and 2V thresholds. Verify that the thermal performance of the 8-DFN package meets the junction temperature requirements under maximum load conditions.
Part Context
This part belongs to the NCP5901B series of gate drivers. It shares functional similarities with variants like NCP5901BDR2G but differs in package type, utilizing an 8-DFN form factor instead of SOIC-8. The series is tailored for efficient power management ICs requiring precise gate control.
Replacement Considerations
Public confirmed substitute part numbers are not available in the provided documentation. Consider checking for direct pin-compatible alternatives within the same manufacturer's portfolio if obsolescence occurs.
