MAX40203 Evaluation Kit Evaluates: MAX40203 General Description Features The MAX40203 evaluation kit (EV kit) provides a proven Drops Only 100mV at 500mA design to evaluate the MAX40203 ideal-diode. This EV Less than 10nA Leakage When Reverse-Biased kit demonstrates the MAX40203 in a space-saving 5-pin From V DD SOT23 (MAX40203AUK+). This EV kit can be used to Supply Voltage Range: Between 1.2V and 5.5V evaluate the MAX40203AUK+ as well. Low Supply Quiescent Current: 300nA (typ), The MAX40203 EV kit PCB comes with two 500nA (max) MAX40203AUK+ devices installed. The MAX40203 device is a current-switch, which drops so little voltage as Thermally Self-Protecting to approximate an ideal diode. -40C to +125C Temperature Range The MAX40203 is also available in a tiny 0.8mm x 0.8mm Evaluates MAX40203AUK+ 4-bump WLP with a 0.35mm bump pitch and has lower Accommodates Easy-to-Use Components voltage drop. These devices operate over the automotive Proven PCB Layout -40C to +125 C temperature range. Fully Assembled and Tested Ordering Information appears at end of data sheet.
