PBY306 Datasheet PWM Control Scheme The MAX887 uses an oscillator-triggered minimum/ maximum on-time current-mode control scheme. The minimum on-time is approximately 280ns unless in dropout. The maximum on-time is approximately 4/fOSC, allowing operation t0 100% duty cycle. Current- mode feedback provides cycle-by-cycle current limit- ing for superior load and line response and protection of the internal MOSFET and rectifier. PBY306 Price

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. |
