NOTE:
DON'T USE any Ni-Cd, Ni-MH, and Pb battery types directly
connected with ME910C1. Their use can lead to overvoltage on the
ME910C1 and damage it. USE ONLY Li-Ion battery types.
4.3.2. Thermal Design Guidelines
Worst case as reference values for thermal design of ME910C1 are:
 Average current consumption: 800 mA
 Supply voltage: 3.80V
NOTE:
Make PCB design in order to have the best connection of GND pads
to large surfaces.
NOTE:
The ME910C1 includes a function to prevent overheating.
4.3.3. Power Supply PCB layout Guidelines
As seen on the electrical design guidelines the power supply shall have a low ESR
capacitor on the output to cut the current peaks on the input to protect the supply from
spikes The placement of this component is crucial for the correct working of the circuitry.
