LP3929TME-AACQ/NOPB

Translators, Level Shifters Overview

The LP3929TME-AACQ/NOPB is a high-speed bi-directional level shifter and ultra-low-dropout CMOS voltage regulator designed for portable applications. It translates 1.8 V LVCMOS signals on the host side to 2.85 V LVCMOS levels on the card side, supporting miniSD/SD 4-bit data buses. The integrated LDO provides up to 200 mA from a 3.05 V to 5.5 V input range. Key electrical parameters include a typical propagation delay of 3 ns, a maximum channel-to-channel skew of 1 ns, and thermal shutdown at 160°C. It operates within an ambient temperature range of -30°C to +85°C.

Translators, Level Shifters Feature Summary

• Integrates six-signal level translation with independent direct control over CMD, Data0, and Data1-3 paths to support mini SD state machine requirements.
• Features Application Specific Integrated Passives (ASIP) including integrated pull-ups, pull-downs, series resistors, and capacitors for EMC filtering on the card side.
• Provides robust IEC ESD protection rated at ±15 kV air gap and ±8 kV direct contact on the B-side ports.
• Includes a low-dropout regulator stable with small ceramic and high-quality tantalum output capacitors.

Translators, Level Shifters Applications

• Portable devices requiring simultaneous level translation and power generation in a compact footprint
• MiniSD or SD 4-bit bi-directional data bus interfaces
• Battery-powered wireless applications

Translators, Level Shifters Procurement Notes

Verify the specific suffix AACQ against the latest Texas Instruments Package Option Addendum to confirm current manufacturing status and lead finish specifications. Ensure that design implementations account for DSBGA light sensitivity by avoiding exposure to direct sunlight or halogen lamps during operation. Confirm that external capacitor selections meet the specified stability ranges for both capacitance values and equivalent series resistance.

Translators, Level Shifters Selection Notes

Select this component when a single package solution is required for both 1.8 V to 2.85 V level shifting and regulated power supply generation. It is suitable for designs prioritizing minimal board space due to its ultra-small DSBGA 24 bump package. Consider the integrated ASIP features if EMC filtering components need to be minimized on the printed circuit board layout.

Translators, Level Shifters Part Context

This device belongs to the LP3929 family, which combines high-speed logic level shifting capabilities with power management functions. It is specifically engineered for mobile phone and wireless applications where space constraints are critical. The integration of the LDO and level shifters allows for simplified system architecture by reducing the total number of discrete components required.
