7.6 Battery Monitor (BATMON)
The main features of the battery monitor are:
Configurable voltage threshold from 1.7 V to 3.675 V
Generation of an interrupt when supply voltage drops below the threshold
Current state can be monitored in a register bit
7.6.1 Overview
The battery monitor (BATMON) detects and indicates a low voltage of the external
supply voltage at pin 28 (EVDD). This is done by comparing the voltage on the external
supply pin 28 (EVDD) with a configurable internal threshold voltage. A simplified
schematic of the BATMON with the most important input and output signals is shown in
Figure 7-14. Simplified Schematic of BATMON
7.6.2 Configuration
The BATMON can be configured using the register 0x11 (BATMON). Register subfield
BATMON_VTH sets the threshold voltage. It is configurable with a resolution of 75 mV
in the upper voltage range (BATMON_HR = 1) and with a resolution of 50 mV in the
lower voltage range (BATMON_HR = 0); for details, refer to register 0x11 (BATMON).
7.6.3 Data Interpretation
The register bit BATMON_OK of register 0x11 (BATMON) represents the current value
of the supply voltage:
If BATMON_OK = 0, the supply voltage is lower than the threshold voltage.
If BATMON_OK = 1, the supply voltage is higher than the threshold voltage.
After setting a new threshold, the value BATMON_OK should be read out to verify the
current supply voltage value.
Note, the battery monitor is inactive during P_ON and SLEEP states, see status register
0x01 (TRX_STATUS).
7.6.4 Interrupt Handling
A supply voltage drop below the configured threshold value is indicated by interrupt
IRQ_7 (BAT_LOW), see section 4.7. Note that the interrupt is issued only if
BATMON_OK changes from 1 to 0.
No interrupt is generated when
