Attention: Power drawn from V_24V, and V_1V8_PMIC_OUT
The current drawn from V_24V (pin 2) is added to the current consumption of the rest of the
TQMLS1012AL. The user must provide any additional power required at the voltage input of the
TQMLS1012AL and observe the load capacity of the fuse.
The power taken from V_1V8_PMIC_OUT (pin 8) is added to the power consumption at V_3V3_IN
(balls G14, H4, J14) of the TQMLS1012AL.
If power is taken from V_1V8_PMIC_OUT and there are doubts about the existing utilization of the
V_3V3 power budget, the external current consumption at V_3V3 (e.g. at pins 2 and 11 of header
X22) must be restricted accordingly.
V_1V8_PMIC_OUT supplies critical components on the TQMLS1012AL. If this voltage is used
to supply external components, make sure that the function of the TQMLS1012AL is not impaired.
This can be achieved by filtering V_1V8_PMIC_OUT on the carrier board using a suitable circuit.
