MAX40203EVKIT#: 1.2 ~ 5.5V @ 1A, Ideal Diode-OR Controller

Summary

The MAX40203 evaluation kit (EV kit) provides a proven design to evaluate the MAX40203 “ideal-diode”. This EV kit demonstrates the MAX40203 in a space-saving 5-pin SOT23 (MAX40203AUK+). This EV kit can be used to evaluate the MAX40203AUK+ as well.

The MAX40203 EV kit PCB comes with two MAX40203AUK+ devices installed. The MAX40203 device is a current-switch, which drops so little voltage as to approximate an “ideal diode”.

The MAX40203 is also available in a tiny 0.8mm x 0.8mm 4-bump WLP with a 0.35mm bump pitch and has lower voltage drop. These devices operate over the automotive -40°C to +125° C temperature range.

Drops Only 100mV at 500mA
Less than 10nA Leakage When Reverse-Biased From VDD
Supply Voltage Range: Between 1.2V and 5.5V
Low Supply Quiescent Current: 300nA (typ), 500nA (max)
Thermally Self-Protecting
