SIL6401IB Datasheet
SIL6401IB on stock 2.2.4 COAXIAL PROBES Another type of internal probe is the coaxial probe (Figure 2-10); these are most useful with oils or similar fluids having a low dielectric constant; the inner rod is connected to the signal connection, and together with the outer grounded cylinder forms a capacitor whose dielectric is either air or oil. Keeping the gap between rod and cylinder to a minimum increases the 'gain' of the electrode. For cases where there are multiple batteriesto be charged, the LTC1729 detects when a batte ry is removed and resets the timers for the next charge cycle. The battery present detection is the primary function of comparator COMP2. When the battery is disconnected from the LTC1729, the voltage at the BAT pin will begin ramping upward. This is due to a current source inside the charger or an external pull-up resistor. Once the voltage on the BAT pin exceeds the 4.5V/cell limit, COMP2 signals a VMAX = true to the logic and turns on a transistor that clamps the voltage. |
