Overview
The UCC21520ADW is a dual-channel galvanically isolated gate driver manufactured by Texas Instruments in a 16-pin SOIC package. It provides independent high-side and low-side drive channels with peak output currents of 4A and 6A respectively. The device features a 5700 Vrms isolation voltage rating and operates within a supply voltage range of 3V to 18V for the input side and 6.5V to 25V for the output side. Key electrical parameters include propagation delays up to 30ns, rise times of 6ns, and fall times of 7ns. It supports CMOS and TTL logic inputs and functions across an industrial temperature range from -40°C to +125°C.
Feature Summary
- Provides dual-channel isolation for independent high-side and low-side switching control
- Features fast dynamic response with nanosecond-scale rise and fall times
- Includes dedicated disable pin functionality for system safety management
Applications
- Industrial motor drives and inverters
- Solar micro-inverter systems
- Uninterruptible power supplies (UPS)
- High-frequency DC-DC converters
Procurement Notes
Verify the specific suffix 'DW' confirms the SOIC-16 tube packaging variant distinct from the 'ADWR' tape-and-reel version. Confirm RoHS compliance status and lead times directly with authorized distributors as availability fluctuates. Ensure ESD handling protocols are followed during assembly due to the sensitivity of the isolation barrier components.
Selection Notes
Select this component when dual-channel isolation is required for bridge topologies. Compare against the UCC21520DW if standard commercial grade suffices, or consider the ADWR variant for automated surface-mount assembly needs. Evaluate thermal dissipation requirements given the 1.05W power rating in the SOIC-16 footprint.
Part Context
This part belongs to the UCC21520 family of universal isolated gate drivers designed for robust performance in noisy environments. It utilizes capacitive isolation technology to provide high common-mode transient immunity. The device integrates internal pull-up/pull-down resistors to ensure defined states during startup or fault conditions.
Replacement Considerations
Direct substitutes include the UCC21520DW for identical specifications in different packaging contexts. Verify pinout compatibility before replacing with other isolated driver families.
