Datasheet - AS8515 To p Die Overview
7.11 Initialization
When the power supply is switched on, when VSUP > VSUVR_OFF, RESET_VSUP_N becomes high. This starts the regulator LDO with 3.3V
and Vuvr_off option of 2.75V. When VCC > Vuvr_off (2.75V), active-low PORN_2_OTP is generated. The rising edge of PORN_2_OTP loads
contents of fuse onto the factory setting latch after load access time TLoad. LOAD_OTP_IN_PREREG signal loads contents of factory setting
latch onto a register. This register provides the actual settings of LDO, Vuvr_off and Reset Timeout period TRes. This is done as the factory
setting block is powered by the VCC. If VCC > Vuvr_off (phase 2), Reset timeout is restarted. RESET signal is de-asserted after Reset Timeout
period TRes (phase 2) and then device enters into normal mode. The circuit also needs to initialize correctly for very slow ramp rates on VSUP (of
the order of 0.5V/min).
