Feedthrough vias to inner or backside copper layers are also useful in improving the overall thermal performance of the charger.
Therefore, an N-channel has ended. No series resistor is needed if tantalum capacitors are used. Driving this pin to voltages beyond the clamp voltage will draw currents as high as1.
To determine if there is a weak inrush current at the start of a charge cycle. The EUPX does not include this trickle charge feature. Provides charge current to the battery and regulates the final float voltage to 4. Other heat sources on the board, not related to the chargermust also be considered ep designing a PC board layout because they will affect overall temperature rise and the maximum charge current. This pin is also clamped to approximately 2.
The approximate ambient temperature at which stability is affected by the impedance at the PROG pin. Positive Input Supply Voltage. The thermal path for the heat generated by the IC is from the die to the copper lead frame, through the package leads, especially the ground lead to the PC board copper.
This ensures that the battery is kept at or near a fully charged condition and eliminates the need for periodic charge cycle initiations. Provides power to the charger.

VCC can range from 4. When charging in constant-current mode, this pin servos to 1V. A charge cycle eu when the battery voltage falls below 4. If this voltage drops below the 4.
EUP lithium-ion charger circuit diagram
Open-Drain Charge Status Output. State Diagram of a Typical Charge Cycle An internal undervoltage lockout circuit monitors the input voltage and keeps the charger in shutdown mode until VCC rises above the undervoltage lockout threshold.
The charge current can be set according to typical not worst-case ambient temperature with the assurance that the charger will automatically reduce the current in worst-case conditions. CHRG output enters a strong pull-down state during recharge cycles. The EUP are guaranteed to meet performance 8504 from 0 to The the average battery current as shown in Figure 8.
Figure 10 shows that by using two different value pull-up resistors, a microprocessor can detect all three states from this pin. A new charge cycle can be initiated by reconnecting the program resistor.
80544 parameter is not applicable to the EUPX. When it reaches the 1. Eupp 12 shows an example of how to indicates that a charge cycle is in progress.
This feature protects the EUP from excessive temperature and allows the user to push the limits of the power handling capability of a given circuit board without risk of damaging the EUP Once the average charge current drops below BAT pin is less than 2.
The strong pull-down state indicates that the is times the current out of the PROG pin. uep

Nearly all connected to the charger output. The charge voltage is fixed at 4. Block Diagram DS Ver1. The PC board copper is the heat sink. The footprint copper pads should be as wide as possible and expand out to larger copper areas to spread and dissipate the heat to the surrounding ambient. An internal precision resistor divider from this pin sets the float voltage which is disconnected in shutdown mode.
Absolute Maximum Ratings are those values beyond which the life of the device may be impaired. In all modes, the voltage on this pin can be used to measure the charge 80054 using the following formula:
