Analog Devices Inc./Maxim Integrated MAX14515AEWA+T

Overview

MAX14515AEWA+T from Maxim Integrated is a high-voltage liquid lens driver IC with differential 42VRMS (min) output at 1.0kHz into 220pF, controlled via I²C interface, featuring an 8-bit monotonic DAC and shutdown current ≤500nA. It operates from +2.7V to +5.5V and is designed for compact camera module integration.

For engineers reviewing the MAX14515AEWA+T datasheet, MAX14515AEWA+T pinout, MAX14515AEWA+T application, or MAX14515AEWA+T equivalent, key selection criteria include RMS output voltage capability, I²C-controlled DAC resolution, WLP package footprint, power-saving mode behavior, and ESD robustness on high-voltage outputs.

Technical Context

The MAX14515AEWA+T integrates a charge-pump boost converter and H-bridge to generate high-voltage differential output without external inductors. Its 8-bit DAC sets output amplitude with guaranteed monotonicity, and I²C register mapping enables precise lens actuation control in real time.

Two low-power states are implemented: shutdown mode disables I²C and resets registers (<500nA), while sleep mode retains POR functionality and draws <3µA during I²C inactivity. Operation over –40°C to +85°C supports mobile imaging environments.

FAQ

What is the maximum output voltage capability of the MAX14515AEWA+T?

The MAX14515AEWA+T delivers up to 42VRMS minimum into a 220pF liquid lens load at 1.0kHz. This is measured under specified conditions per the official datasheet (Rev 0, 2008). The actual peak-to-peak voltage exceeds 120V, enabling reliable actuation of commercially available electrowetting lenses. Output amplitude is digitally set via its 8-bit I²C-controlled DAC.

Does the MAX14515AEWA+T require external inductors or transformers?

No, the MAX14515AEWA+T integrates a charge-pump-based boost converter and H-bridge, eliminating the need for external inductors or transformers. This allows full high-voltage generation using only small ceramic capacitors. The design reduces solution size and simplifies layout-critical for camera modules where board area is at a premium. All power conversion circuitry is contained within the IC.

How does the power management of the MAX14515AEWA+T support battery-powered devices?

The MAX14515AEWA+T supports two ultra-low-power states: shutdown mode draws ≤500nA and resets all registers, while sleep mode maintains POR functionality and consumes <3µA during I²C inactivity. Both modes enable aggressive power gating in smartphones and portable medical devices. The EN pin allows hardware-controlled entry/exit, and I²C activity automatically wakes the device from sleep.

Is the MAX14515AEWA+T compatible with standard I²C buses?

Yes, the MAX14515AEWA+T implements a standard I²C-compatible 2-wire interface with SCL and SDA pins operating at 1.8V–5.5V logic levels. It supports standard-mode (100kHz) and fast-mode (400kHz) speeds. No level shifting is required when interfacing with common baseband processors or microcontrollers. Register maps and ACK/NACK behavior conform to I²C specification Rev. 6.

What package type and dimensions does the MAX14515AEWA+T use?

The MAX14515AEWA+T uses an 8-bump Wafer-Level Package (WLP) measuring 1.0mm × 2.0mm with 0.4mm pitch. This ultra-compact package is qualified for reflow soldering and designed for direct placement adjacent to liquid lens elements in camera modules. The NC bump must remain unconnected, and thermal pads are not included-board-level thermal relief relies on copper pour under the package.
