Overview
The UCC37325DGNR is a dual low-side power MOSFET gate driver manufactured by Texas Instruments. It features two independent drivers with hysteretic logic for high-speed switching. The device provides a peak output current of 4 A and operates within a supply voltage range of 4 V to 15 V. Typical rise and fall times are 23 ns. It functions in an ambient temperature range from 0°C to +70°C. The component utilizes a PowerPAD MSOP-8 surface-mount package.
Feature Summary
- Dual channel configuration with independent control inputs
- Hysteretic logic design for fast switching performance
- Totem-pole output stage capable of sourcing and sinking 4 A
Applications
- Power MOSFET switching in DC-DC converters
- Gate drive circuits for motor control systems
- Inverter bridge driver stages
Procurement Notes
Verify the specific suffix 'RG4' against the manufacturer's latest documentation to confirm RoHS compliance status and lead time requirements. Ensure the ordering part number matches the exact package variant required for the PCB footprint. Confirm availability through authorized distributors as production status may vary.
Selection Notes
Select this component when a dual low-side driver with moderate speed and 4 A peak current is required. The hysteretic logic input allows for direct interfacing with standard logic levels without additional pull-up resistors. Consider thermal dissipation capabilities of the PowerPAD package for high-frequency applications.
Part Context
This device belongs to the UCC3732x series of high-speed gate drivers. It shares architectural similarities with the UCC37323 and UCC37324 but differs in output polarity configuration. The series is designed for efficient power management in compact electronic systems requiring reliable MOSFET switching.
Replacement Considerations
UCC37325DGN is the tube-packaged equivalent of the same functional device. UCC37323DGNR offers similar electrical characteristics but with different output inversion logic. Verify pin compatibility and logic polarity before substituting.
