Description

The LP3929 is designed for portable and wireless applications requiring level translation and power supply generation in a compact footprint.

The LP3929 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. A shutdown pin is provided for the level shifters and regulator. The f_CLK_A is a feedback clock to the host which can be used to overcome level shifter bus delay.

The built-in low-dropout voltage regulator is ideal for mobile phone and battery powered wireless applications. It provides up to 200 mA from a 3.05 V to 5.5 V input. It is stable with small 1.0 F ±30% ceramic and high quality tantalum output capacitors, requiring smallest possible PC board area.

The card (B port) side channels have integration of ASIP (Application Specific Integrated Passives) - 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 discharge, ±8 kV direct contact.
