Hi. I am looking for a management IC which has pushbutton control, USB powerpath, Li-ion charger, in-built LDO and load current capacity upto 1A pulse spikes. The load might contain an OLED display, WiFi module and vibration motor. Please provide me the options available. I am using 3.7V, 400mAh battery. I looked at LTC3553 but I am not sure if that will suit my application. Please confirm. Thanks!
