MP1907GQ-Z

Overview

The MP1907GQ-Z is a half-bridge gate driver manufactured by Monolithic Power Systems. It features two independent drivers with non-inverting input logic, designed for driving N-channel MOSFETs. The device supports a high-side voltage up to 100 V via bootstrap operation and operates within a supply voltage range of 4.5 V to 18 V. It delivers peak output currents of 2.5 A for both sourcing and sinking. Typical switching characteristics include rise and fall times of 12 ns and 9 ns, respectively. The component is housed in a 10-QFN (3x3 mm) package with an exposed pad and functions reliably across a junction temperature range of -40°C to +125°C.

Feature Summary

• Supports high-side voltages up to 100 V using bootstrap configuration
• Delivers symmetrical 2.5 A peak source and sink current capability
• Features fast switching performance with typical 12 ns rise and 9 ns fall times
• Operates with non-inverting logic inputs compatible with standard digital signals

Applications

• Motor control systems requiring half-bridge configurations
• Power factor correction circuits
• DC-DC converter topologies utilizing high-side N-channel MOSFETs

Procurement Notes

Verify the specific suffix 'Z' indicates RoHS compliance when ordering. Confirm that the 10-QFN package dimensions match the target PCB footprint. Ensure the design accommodates the required bootstrap capacitor and high-side drive voltage requirements for the intended load. Check for any specific handling instructions related to the exposed thermal pad on the QFN package.

Selection Notes

Select this component when a robust half-bridge driver with high voltage tolerance is required. The 2.5 A output current is suitable for medium-power applications. Consider the 10-QFN package size for space-constrained designs. Verify that the operating supply voltage range of 4.5 V to 18 V aligns with the system's available power rails. Ensure the non-inverting logic interface matches the control signal polarity.
