Overview

  • Save Critical Voltage Drop in Portable Application
    • Drops Less Than 43mV at 500mA; 85mV at 1A
  • Longer Battery Life
    • Low Leakage When Reverse-Biased: 70nA (Typ), 1.5µA (Max)
    • Low Supply Quiescent Current: 7µA (Typ), 18µA (Max)
  • Saves Space Over Larger Schottky Diodes
    • Tiny 0.73mm x 0.73mm 4-bump WLP
    • SOT23-5 Package
  • Supply Voltage Range 1.5V to 5.5V
  • Thermally Self-Protecting
  • -40°C to +125°C Temperature Range

The MAX40200 is an ideal diode current-switch that drops so little voltage that it approaches an order of magnitude better than Schottky diodes.

When forward-biased and enabled, the MAX40200 conducts with as little as 85mV of voltage drop while carrying currents as high as 1A. Typical voltage drop is 43mV at 500mA, with the voltage drop increasing linearly at higher currents. The MAX40200 thermally protects itself, and any downstream circuitry, from overtemperature conditions.

When disabled (EN = low) the MAX40200 blocks voltages up to 6V in either direction, making it suitable for most low-voltage, portable electronic devices. The MAX40200 operates from a supply voltage of 1.5V to 5.5V.

The MAX40200 is available in a tiny, 0.73mm X 0.73mm, 4-bump wafer-level package (WLP), with a 0.35mm bump pitch and only 0.5mm high and 5-pin SOT-23 package. The MAX40200 operates over the extended -40°C to +125°C temperature range.

Product Details

The MAX40200 evaluation kit (EV kit) provides a proven design to evaluate the MAX40200 “ideal-diode”. This EV kit demonstrates the MAX40200 in a tiny, space-saving 4-bump wafer-level package (WLP). The MAX40200 is also available in a 5-pin SOT23 (MAX40200AUK+), which is not compatible with this EV kit.

The MAX40200 EV kit PCB comes with two MAX40200ANS+ devices installed. The MAX40200 device is a current-switch, which drops so little voltage as to approximate an “ideal diode”.

The MAX40200 parts are available in a tiny 0.73mm × 0.73mm 4-bump WLP with a 0.35mm bump pitch and is only 0.5mm high. It operates over the extended -40°C to +125°C temperature range.

  • Electronic Toys
  • Notebook and Tablet Computers
  • Portable Media Players
  • Portable/Wearable Medical Devices
  • USB-Powered Peripherals
