40V Complementary N+P Dual MOSFET —— CEU4269 Usage Guide

The CEU4269 is HeroMicro a high-performance dual-channel MOSFET integrating both an N-channel and a P-channel device in a single package, fabricated using advanced trench technology. Designed for applications requiring complementary switching—such as motor control, battery protection, power path selection, and H-bridge drivers—it delivers ultra-low on-resistance, low gate charge, and excellent switching performance in space-constrained, high-efficiency systems.

2. Key Usage Guidelines

(1) Ideal for Half-Bridge / H-Bridge Circuits

  • The N+P pair enables single-supply H-bridge or half-bridge designs without bootstrap circuits, simplifying gate drive.

  • Perfect for bidirectional motor control, battery charge/discharge FETs, and load switches.

(2) Logic-Level Compatible

  • N-channel turns on fully at 4.5 V (RDS(ON) < 35 mΩ); P-channel at –4.5 V (RDS(ON) < 52 mΩ).

  • Can be driven directly from 3.3V/5V logic with simple level-shifting or dedicated dual drivers.

  • For high-side P-MOS, ensure sufficient |VGS| even when source floats.

(3) Low Qg Enables High-Speed Switching

  • Ultra-low gate charge (12 nC N, 9 nC P) supports fast switching (N: tr=3 ns, tf=2 ns) and high-frequency operation (>100 kHz).

(4) Body Diode Characteristics

  • N-diode: VSD ≤ 1.2 V @ 3 A; P-diode: VSD ≤ –1.0 V @ –1 A.

  • Suitable for freewheeling in low-power inductive loads.

(5) Thermal Design

  • RθJC of 4.5 °C/W (N) and 6 °C/W (P) indicates good thermal conduction.

  • Evaluate need for heatsinking based on power dissipation and ambient conditions.

3. Typical Applications

  • Battery pack charge/discharge FET pair (BMS) in portable devices

  • Small DC motor H-bridge drivers (toys, robotics, cooling fans)

  • USB Type-C power path selection and overvoltage protection

  • Low-voltage synchronous buck POL converters

  • Bidirectional switches in industrial I/O modules

4. Summary

The CEU4269 stands out with its integrated N+P architecture, 40V/20A & 12A ratings, ultra-low RDS(ON), low Qg, and logic-level compatibility. When paired with robust gate driving and appropriate thermal management, it provides a highly integrated, efficient, and reliable solution for bidirectional power control in consumer electronics, IoT, and industrial systems
