There are two LDO internal the MAXM17537.The VCC is powered by INLDO if EN/UVLO is higher than 0.8V after start-up. The VCC is powered by EXTVCC when VCC is higher than its threshold and EXVCC is higher…
The MAXM17537 has two internal low-dropout (LDO) regulators that power VCC. During power-up, when the EN/UVLO pin voltage is above the true shutdown voltage (0.8V), then the VCC is powered from INLDO.…
