LP3929 Overview
The LP3929 is designed for portable and wireless applications requiring level translation and power supply generation in a pact footprint. The device level translates 1.8 V LVCMOS on the host (A) side to 2.85 V LVCMOS levels on the card (B) side for a miniSD / SD 4-bit bi-directional data bus. Independent direct control of the CMD, Data0 and Data1-3 paths support mini SD state machine requirements.
LP3929 Applications
- on chip integrated pull-up, pull-down, series resistors and capacitors for EMC filtering. It is designed to tolerate IEC61000-4-2 level 4 ESD: ± 15 kV air disch
