The parameter t_ON(VS) is defined at Pos. 10.2.13. The parameter t_OFF(VS) depends on the load and supply voltage
V_BATT characteristics.
5.3
EN Unused
In case of an unused EN pin, there are two different ways to connect it:
5.3.1 EN - Pull Up to VS
The EN pin can be connected with a pull up resistor (e.g. 10 kΩ) to V_s potential. In this configuration the LITIX^TM
Basic IC is always enabled.
5.3.2 EN - Direct Connection to VS
The EN pin can be connected directly to the VS pin (IC always enabled). This configuration has the advantage
(compared to the configuration described in Chapter 5.3.1) that no additional external component is required.
