UCC37325P

Overview

The UCC37325P is a dual high-speed low-side power MOSFET driver manufactured by Texas Instruments. It features two independent outputs capable of delivering a peak drive current of 4 A. The device operates within a supply voltage range of 4 V to 15 V and utilizes hysteretic logic for fast switching, with typical rise and fall times of 23 ns. Designed for surface-mount applications, it is housed in an 8-pin MSOP PowerPAD package. The component supports both inverting and non-inverting output configurations and functions within an operating temperature range of 0°C to +70°C.

Procurement Notes

Verify the specific suffix against official documentation to confirm pinout compatibility and electrical specifications. Ensure the selected variant matches the required thermal management strategy for the target application environment. Cross-reference the manufacturer's latest datasheet revision to validate all operational limits before finalizing procurement decisions.

Selection Notes

Select this component when dual low-side driving is required with moderate current capabilities. The MSOP PowerPAD package offers a compact footprint suitable for space-constrained designs. Consider the 4 A peak current rating relative to the gate charge requirements of the intended MOSFETs to ensure adequate switching performance without exceeding thermal limits.

Part Context
