I EN Enable
ON: The AS1310 is enabled
OFF: The AS1310 is disabled
No Jumper: Connect a valid enable signal
to the pin in the middle
J LBI Low Battery Input
Vin: The LBI monitors VIN via a resistive divider
→ LBO goes low, if LBI threshold (0.6V) is
reached
GND: The LBI pin is connected to GND
LBO works like a POK
This Jumper may not be left floating
4 Getting Started
The AS1310 Demoboard is designed to work with all available AS1310 versions.
With the resistor divider R1/R2 it is possible to adjust the threshold of the monitored Vin.
On this Demoboard there are no resistors R1/R2 mounted. This should be done by the user.
