96 / 225 page  DA6021 HIGHLY INTEGRATED POWER MANAGEMENT IC FOR INTEL® ATOM™ Z3000 PROCESSOR Company Confidential Data Sheet Version 3.A - Final 31-Jan-14 © 2014 Dialog Semiconductor GmbH 96 of 224 www.dialog-semiconductor.com V1P8SX: This power rail is used to source platform devices such as eMMC, camera, audio codecs … The maximum allowed output current is defined to 240mA. DA6021 controls this power rail while deriving the information from SoC SLP_S0ix_B signal and switching the rail internally. The typical RDSon of this internal switch is 100mΩ. Description Value [max, m Ω] Val Input power path board resistance 10 - Output power path board resistance 20 - Input, output rails wirebond & internal FET RDS-ON 147 A,D,E Table 52: V1P8S Power Switch Specification Register Name V1P8SX_CTRL Address 0x5D Page 1 Read/Write Reset Value 0x02 MSB LSB R R R R R R R/W R/W Reserved V1P8SX _SEL V1P8SX _EN V1P8SX_EN 0 1 V1P8SX off V1P8SX on V1P8SX_SEL 0 1 V1P8SX controlled by SLP_S0iX_B according to sequencing V1P8SX controlled by V1P8SX_CTRL.V1P8SX_EN bit Regardless of V1P8SX_EN and V1P8SX_SEL, V1P8SX is disabled when SLP_S3_B is asserted, means low V1PSX_CTRL.
