42 / 86 page  NXP Semiconductors PCF85363A Tiny Real-Time Clock/calendar with 64 byte RAM, alarm function, battery switch-over time stamp input, and I2C-bus 7.11.3.2 Switching at the VBAT level, BSM[1:0] = 01 aaa-010425 internal power supply cleared via interface BSF Vth VDD (= 0 V) VBAT VDD INTA battery mode indication interface active interface inactive interface active I2C Figure 24. Switching at VBAT 7.11.3.3 Switching at the higher of VBAT or Vth level, BSM[1:0] = 10 With this mode switching takes place when VDD falls below the higher of Vth or VBAT. In Figure 25, an example is given where the threshold is set to 1.5 V and a single cell battery is connected to VBAT. In this example, switching to the battery voltage takes place when VDD falls below Vth. PCF85363A All information provided in this document is subject to legal disclaimers. © NXP B.V. 2021.
