NCP303151MNTWG

Overview

The NCP303151MNTWG is an integrated driver and MOSFET with an integrated current monitor, manufactured by onsemi. It combines a high-side MOSFET, a low-side MOSFET, and a gate driver into a single PQFN-39 package. The device features a 30 V / 30 V breakdown voltage for the MOSFETs and supports switching frequencies up to 1 MHz. It delivers peak output currents of 50 A and 80 A. The supply voltage range is 4.5 V to 5.5 V, with a typical operating quiescent current of 8 mA. Propagation delay is maximized at 75 ns. The component operates within a temperature range of -40°C to +125°C.

Feature Summary

• Integrates high-side and low-side MOSFETs with a dedicated gate driver in a single compact package to reduce parasitic effects and board space.
• Includes an internal bootstrap diode and precise current monitoring capabilities with over-zero detection options.
• Supports 3.3 V or 5 V PWM inputs with correct response to three-level PWM signals.
• Features under-voltage lockout and shutdown functionality for enhanced system protection.

Applications

• High-current DC-DC buck power conversion applications
• Power management modules requiring integrated gate driving and switching
• Systems compatible with Intel PowerState 4

Procurement Notes

Verify the specific ordering suffix MNTWG to ensure the correct PQFN-39 package configuration. Confirm that the design accommodates the NRND (Not Recommended for New Designs) status if applicable to long-term production plans. Ensure input logic levels match the specified 3.3 V or 5 V compatibility. Validate thermal requirements against the maximum junction temperature limits during operation.

Selection Notes

Select this component when minimizing PCB area and parasitic inductance is critical for high-frequency switching performance. It is suitable for designs requiring integrated current sensing without external shunt resistors. Consider the 30 V rating for appropriate voltage headroom in low-voltage DC-DC topologies. Evaluate the trade-off between integration benefits and the NRND status for future-proofing.
