2EDN7424F
Fast dual-channel 4A gate driver optimized for driving both standard and superjunction MOSFETs, as well as GaN power switching devices.
描述:
The input signals are low voltage TTL and 3.3V CMOS-compatible with a very broad voltage handling capability of up to +20V and down to -10VDC. The unique ability to handle -10VDC at the input pins protects the device against ground bouncing. Each of the two outputs is able to sink and source a 4A current utilizing a true rail-to-rail output stage, which ensures very low impedances of 0.7Ω up to the positive and 0.55Ω down to the negative
rail respectively.
Excellent channel to channel delay matching, typ. 1ns, enables risk-free doubling of the source and sink capability up to 10A peak through paralleling of both channels. The combination of industry standard pin-outs and different logic input/output configurations guarantee high flexibility and shortens R&D time. The gate driver is available in the three package options: PG-DSO-8-pin, PG-VDSON-8-pin and PG-TDSSO-8-pin (small form-factor, improved thermal performance compared to DSO-8).
