MAX16923 Automotive Display PMICs

Analog Devices Inc. MAX16923 Automotive Display PMICs are 4-channel power-management ICs designed to accommodate the main rails used in modern automotive TFT displays. The MAX16923 integrates a high-voltage Buck converter that transforms battery voltages into a 5.0V or 3.3V intermediate rail. In addition, a high-voltage, always-on, low-quiescent-current linear regulator supplies power at 3.3V. The low-voltage section comprises a fully-integrated DC-DC converter and an LDO running off the intermediate rail. In addition, an integrated watchdog timer guards against runaway code.
