NCP4423P

Overview

The NCP4423P is a high-speed, low-side MOSFET driver designed for automotive applications. It features a peak output current of 1.5 A and supports supply voltages from 4.5 V to 26 V. The device includes an adjustable dead-time control function ranging from 0 ns to 100 ns to prevent shoot-through currents in half-bridge configurations. It incorporates robust protection mechanisms such as under-voltage lockout (UVLO), thermal shutdown, and desaturation detection with programmable delay. The component utilizes a SOIC-8 package and complies with AEC-Q100 qualification standards for automotive reliability.

Feature Summary

Integrated adjustable dead-time control to optimize switching performance and minimize cross-conduction losses.
Built-in desaturation fault detection with programmable delay for comprehensive short-circuit protection.
High peak drive capability supporting fast switching speeds for efficient power stage operation.

Applications

Automotive motor control systems
Half-bridge and full-bridge power converter topologies
On-board charger (OBC) gate driving

Procurement Notes

Verify the specific suffix against official onsemi documentation to confirm exact packaging and temperature grade specifications. Ensure that the selected variant aligns with the required automotive qualification standards and intended operating environment conditions before finalizing procurement orders.

Selection Notes

Evaluate the required dead-time range based on the specific MOSFET characteristics and switching frequency targets. Confirm that the input logic voltage levels are compatible with the controlling microcontroller or DSP outputs. Assess the thermal management requirements considering the expected duty cycle and ambient operating temperatures within the target application enclosure.
