TI UCC27524ADR

Low-Side24,5 В ~ 18 В

Overview

The UCC27524ADR device is a dual-channel, high-speed, low-side, gate-driver device capable of effectively driving MOSFET and IGBT power switches. The UCC27524ADR is a variant of the UCC2752x family. The UCC27524ADR adds the ability to handle –5 V directly at the input pins for increased robustness. The UCC27524ADR is a dual non-inverting driver. Using a design that inherently minimizes shoot-through current, the UCC27524ADR is capable of delivering high-peak current pulses of up to 5-A source and 5-A sink into capacitive loads along with rail-to-rail drive capability and extremely small propagation delay typically 13 ns. In addition, the drivers feature matched internal propagation delays between the two channels which are very well suited for applications requiring dual-gate drives with critical timing, such as synchronous rectifiers. This also enables connecting two channels in parallel to effectively increase current-drive capability or driving two switches in parallel with a single input signal. The input pin thresholds are based on TTL and CMOS compatible low-voltage logic, which is fixed and independent of the VDD supply voltage. Wide hysteresis between the high and low thresholds offers excellent noise immunity.

UCC27524A family of devices are available in SOIC-8 (D), VSSOP-8 with exposed pad (DGN) packages.
