PrE | Page 30 of 148 BSO Event (FBSO=1) V -V PN V DCIN V DD SAG LEVEL trip point 2.75V SAG Event (FSAG=1) V Event 1.2V DCIN SAGCYC=1 Automatic Battery switchover V connected to V SW BAT If switchover on low V is enabled, DCIN (FVDC=1) t1 t3 Figure 13: Power Supply Management Interrupts and Battery Switchover with VDD or VDCIN enabled for battery switchover Time Comment t1 TBD Time between when VDCIN goes below 1.2 V and when FVDCIN is raised. t2 TBD Time between when VDD falls below TBD V and when battery switchover occurs. t3 TBD Time between when VDCIN falls below 1.2 V and when battery switchover occurs, if VDCIN is enabled to cause battery switchover. VDCIN_OPT[1:0] in the Battery Switchover Configuration SFR (BATPR, 0xF5) sets this timeout Table 23: Power Supply Event Timings Operating Modes Finally, the transition between VDD and VBAT and the different Power Supply Modes (see Operating modessection) is represented in Figure 15. |
