Q2403A
Description
Note 1: Input offset voltage is defined as the average of the two input offset voltages, measured by forcing first one output, then the other to 1.4V. Input offset current is defined in the same way. Note 2: Input bias current (IB) is defined as the average of the two input currents. Note 3: tPD and ?tPD cannot be measured in automatic handling equipment with low values of overdrive. Correlation tests have shown that tPD and ?tPD limits shown can be guaranteed by design, if additional DC tests are performed to guarantee that all internal bias conditions are correct. For low overdrive conditions, VOS is added to overdrive. Note 4: Input latch setup time, tSU, is the interval in which the input signal must be stable prior to asserting the latch signal. The hold time, tH, is the interval after the latch is asserted in which the input signal must be stable. Q2403A PDF

Applications
The fourth, transient power due to switching current, is caused by the fact that whenever a CMOS device goes through a transition, with VCC 2 VT, there is a time when both N-channel and P-channel devices are both conducting. An expression for this current is derived in Application Note AN-77. The expression is:
Features
The Q2403A is a highly integrated battery charger controller for Li-Ion/Li-Polymer batteries. High Efficiency is achieved by a synchronous buck topology and the use of a MOSFET, instead of a diode, for selecting power from the adapter or battery. The low side MOSFET emulates a diode at light loads to improve the light load efficiency and prevent system bus boosting. |
