Table 39. BSM[1:0] bits - battery switch control (address 26h) bit description
[1]
Default value.
Switching is automatic and controlled by the voltages on the VBAT and VDD pins. There are three modes:
• Compare VDD with an internal reference (Vth)
• Compare VDD with VBAT
• Compare VDD with an internal reference (Vth) and VBAT
The last mode is useful when a rechargeable battery is employed.

Table 40. Battery switch-over modes
Due to the nature of the power switch circuit there is a switching hysteresis (for details, see Figure 24 and
Table 67).
