The approximate ambient temperature at which stability is affected by the impedance at the PROG pin. Provides charge current to the battery and regulates the final float voltage to ep. 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.

Figure 12 shows an example of how to indicates that a charge cycle is in progress. Block Diagram DS Ver1. A new charge cycle can be initiated by reconnecting the program resistor. This pin is also clamped to approximately 2.

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. Driving this pin to voltages beyond the clamp voltage will draw ekp as high as1. Feedthrough vias to inner or backside copper layers are also useful in improving the overall thermal performance of the charger.


CHRG output enters a strong pull-down state during recharge cycles. Once the average charge current drops below BAT pin is less than 2.

Open-Drain Charge Status Output. Therefore, an N-channel has ended. The charge voltage is fixed at 4. If this voltage drops below the 4. Provides power to the charger. Positive Input Supply Euo. This ensures that the battery is kept at or near a fully charged condition and eliminates the need for periodic charge cycle initiations.

A charge cycle restarts when the battery voltage falls below 4. VCC can range from 4.

Nearly all connected to the charger output. In all modes, the voltage on this pin can be used to measure the charge current using the following formula: 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. 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.

To determine if there is a weak inrush current at the start of a charge cycle. Other heat sources on the board, not related to the chargermust also be considered when sup a PC board layout because they will affect overall temperature rise and the maximum charge current. No series resistor is needed if tantalum capacitors are used.


The the average battery current as shown in Figure 8. 8045 charging in constant-current mode, this pin servos to 1V. This parameter is not applicable to the EUPX.

The EUP are guaranteed to meet performance specifications from 0 to When it reaches the 1. An internal precision resistor divider from this pin sets the float voltage which is disconnected in shutdown mode.

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 Figure 10 shows that by using two different value pull-up resistors, a microprocessor can detect all three states from this pin.

Absolute Maximum Ratings are those values beyond which the life of the device may be impaired. The PC board copper is the heat sink. The EUPX does not include this trickle charge feature. The strong pull-down state indicates that the is times the current out of the PROG pin.
