Functional Features
•
•
5V low-drop voltage regulator
Under voltage monitoring with adjustable reset level, VCC1 prewarning and VCC1 short circuit detection
(VRT1/2/3/4, VPW,f ). Please refer to Chapter 15.6 and Chapter 15.7 for more information.
•
•
Short circuit detection and switch off with under voltage fail threshold, device enters SBC Fail-Safe Mode
≥470nF ceramic capacitor at voltage output for stability, with ESR < 1ꢀ @ f = 10 kHz, to achieve the voltage
regulator control loop stability based on the safe phase margin (bode diagram).
•
Output current capability up to IVCC1,lim.
