ABR200 Integration Manual
4.1.2 RF-off
When the RF is not activated, the current consumption is much lower.
Anyway, this is not really a “power saving mode” because the input currents are still in a range
between 80mA (at 4.5V) and 175mA (at 2.2V). Thus it is highly recommended to shut down the
ABR200 completely, after a tag has been read.
4.1.3 Power supply disabled
If the ENABLE pin is disabled (ENABLE lower than 0.4V), the input current is smaller than 4µA.
4.2 Current consumption for 5.0V input voltage
When the ENABLE pin is active (voltage between 1.2V and 5.0V) and the RF-field is activated,
the current consumption of the ABR200 is about 250mA.
In case ENABLE is active but the RF-field is switched off, the current consumption is
approximately 70mA.
If the ENABLE pin is low (voltage lower than 0.4V), the current consumption of the module is less
than 1µA.
