RAA220002GNP#HA0

Gate Driver Overview

The RAA220002GNP#HA0 is a dual high-frequency MOSFET driver designed for synchronous rectified buck applications. It drives upper and lower N-channel power MOSFETs in a half-bridge configuration. The device operates with a supply voltage range of 6 V to 13.2 V and delivers an output current of 1.75 A. Key timing parameters include a rise time of 31 ns, a fall time of 18 ns, a maximum turn-on delay of 38 ns, and a maximum turn-off delay of 23 ns. It functions within a temperature range of -40°C to +85°C and is housed in a 12-lead DFN 3x3 mm package with an exposed pad.

Gate Driver Feature Summary

• Dual channel architecture specifically optimized for driving high-side and low-side N-channel MOSFETs in synchronous buck converters.
• Integrated overvoltage protection mechanism that activates when the supply voltage falls below the Power-On Reset threshold.
• High-speed switching capability with asymmetric rise and fall times to minimize switching losses and improve efficiency.

Gate Driver Applications

• Synchronous rectified DC/DC buck converter circuits
• Half-bridge power stage gate drive interfaces
• High-frequency power management systems

Gate Driver Procurement Notes

Verify the specific suffix #HA0 against the manufacturer's latest datasheet to confirm pinout compatibility and RoHS status. Ensure the ordering information matches the 12-lead DFN 3x3 EP package variant. Cross-reference the part number with official Renesas documentation to validate the operating temperature range and electrical specifications before integration into design files.

Gate Driver Selection Notes

Select this component for designs requiring a dedicated dual gate driver for synchronous buck topologies. The 1.75 A output current supports moderate-power MOSFETs. Consider the 3x3 mm footprint for space-constrained layouts. Verify that the input signal requirements align with the non-inverting logic type specified for this series.

Gate Driver Part Context

This device belongs to the RAA220001 family of gate drivers from Renesas. While similar to the RAA220001, the RAA220002 utilizes a 12-lead 3x3 mm DFN package compared to the 8-lead 2x2 mm variant found in other family members. Both serve as drivers for synchronous rectified buck applications but differ in physical packaging and lead count.

Gate Driver Replacement Considerations

The RAA220001GNP#HA0 is a related family member but uses an 8-lead 2x2 mm DFN package. Direct substitution requires verifying PCB footprint compatibility due to the difference in lead count and package dimensions between the 12-lead and 8-lead variants.

Gate Driver FAQ

What is the specific function of the overvoltage protection feature?

The overvoltage protection engages when the supply voltage (VCC) drops below the Power-On Reset (POR) threshold, ensuring safe operation during undervoltage conditions.

Does this driver support both high-side and low-side MOSFETs?

Yes, it is a dual driver designed to drive both the upper (high-side) and lower (low-side) N-channel MOSFETs in a synchronous buck configuration.
