| Table 80. VBAT monitoring characteristics |
| Symbol | Parameter | Min | Typ | Max | Unit | | R | Resistor bridge for VBAT | - | 50 | - | KΩ | | Q | Ratio on VBAT measurement | - | 2 | - | | Er(1) | Error on Q | -1 | - | +1 | % | T
S_vbat
(1)(2) | ADC sampling time when reading the VBAT
1mV accuracy | 2.2 | - | - | µs |
1. Guaranteed by design.
2. Shortest sampling time can be determined in the application by multiple iterations.
