UCC44273DBVR

Overview

The UCC44273DBVR is a single low-side gate driver manufactured by Texas Instruments, housed in a SOT-23-6 surface-mount package. It operates within a supply voltage range of 4.5 V to 18 V and supports CMOS or TTL logic inputs. The device features industry-standard pinouts and includes a shutdown function. Electrical characteristics include a maximum propagation delay of 26 ns, with rise and fall times of 16 ns and 7 ns respectively. It functions reliably across an operating temperature range from -40°C to +140°C.

Feature Summary

• Single-channel low-side configuration for driving power switches
• Industry-standard pinout compatibility for easy integration
• Integrated shutdown capability for system control

Applications

• Power management systems requiring low-side switching
• Industrial motor control applications
• General-purpose power conversion circuits

Procurement Notes

Verify the specific suffix DBVR corresponds to the SOT-23-6 package and tape-and-reel quantity when ordering. Confirm that the required operating temperature range up to 140°C aligns with your thermal design constraints. Ensure input logic levels are compatible with the specified CMOS or TTL standards to guarantee proper signal integrity during operation.

Selection Notes

Select this component when a compact, single-channel low-side driver is needed with high-temperature resilience. The SOT-23-6 package suits space-constrained designs. Verify that the 18 V maximum supply voltage meets the gate drive requirements of the target MOSFET or IGBT. Consider the 26 ns propagation delay for timing-sensitive applications within the specified logic family constraints.
