NCP1393BDR2G

Full Half-Bridge (H Bridge) Drivers Overview

The NCP1393BDR2G is a high-voltage half-bridge gate driver manufactured by onsemi, designed for driving power MOSFETs in resonant and hard-switched topologies. It integrates an internal oscillator operating at 250 kHz to simplify circuit design. The device features two drivers with a peak output current of 1 A. It operates within a supply voltage range of 8 V to 16 V and supports propagation delays up to 20 µs. Transition times include a rise time of 40 ns and a fall time of 20 ns. The component functions reliably across an extended temperature range from -40 °C to +125 °C and is housed in an 8-pin SOIC package.

Full Half-Bridge (H Bridge) Drivers Procurement Notes

Verify the obsolescence status before procurement, as this component is marked as Not Recommended for New Designs (NRND). Confirm that existing inventory meets long-term support requirements. Ensure compatibility with current PCB footprints and validate that the 8-V minimum supply voltage aligns with system constraints. Check for alternative sources if future production continuity is critical.

Full Half-Bridge (H Bridge) Drivers Selection Notes

Select this driver when a fixed-frequency operation around 250 kHz is required without external timing resistors or capacitors. It is suitable for designs needing integrated bootstrap functionality and moderate drive strength. Consider the NRND status for new projects requiring long-term availability. Verify that the 1-A output current suffices for the target MOSFET gate charge requirements at the intended switching frequency.
