n Detailed Description
The AME2056 is a linear battery charger designed for single cell lithium-ion batteries. The charger has CC/CV modes
with programmable charging current. Charging current is programmed by an external resistor. No blocking diode or
external sense resistor are required.
State Diagram of A Typical Charge Cycle
A charge cycle starts when the VCC pin voltage rises above the UVLO threshold. If the voltage at BAT pin is smaller
than 2.9V, the charger is operating in trickle mode. AME2056 supplies 1/10 programmed current to the battery. When
the BAT pin voltage is greater than 2.9V, the charger enters constant-current mode. The charger supplies the programmed current to the battery. When the voltage at BAT pin approaches the float voltage (4.2V), the charger operates
in constant-voltage mode and the charging current is decreased. A charge cycle is terminated when the charging current
drops below 1/10 programmed current after the float voltage is reached. When the charging current falls below 1/10
programmed charging current for longer than TTERM (1.8ms), charging is terminated. The AME2056 enters in standby
mode.

Setting Charge Current
The charging current can be programmed by a resistor connected from the PROG pin to ground. The battery charging
current is 1200 times the PROG pin flowing out current. The value of required resistor can be calculated by the following
equation:
RPROG =
1200
I CHG ( MAX )
The instantaneous charging current provided to the battery can be determined by monitoring the PROG pin voltage with
the following equation:

Charge status indicator
AME2056 has two status indicators CHRG and STDBY. When the charger is operating in charging status, the CHRG
and STDBY outputs enter strong pull-down and high impedance status, respectively. If the battery is in full status, the
CHRG and STDBY outputs enter high impedance and strong pull-down, respectively. When the TEMP pin voltage is
greater than VTEMP-H or lower than VTEMP-L, the CHRG and STDBY outputs enter high impedance.
When the TEMP pin is short to ground for disable the temperature protection and the battery is not to connect BAT pin,
the light of CHRG and STDBY are flicker and bright, respectively.

Thermal Protection
The internal thermal feedback loop of AME2056 reduces the charging current when the die temperature rises above
approximately 145oC. The function protects the AME2056 from excessive temperature and allow user to push the limits
of the power handing capability without risk of damaging AME2056.

Battery Temperature Fault Monitoring
In the battery over-temperature condition, the charger will turn off the internal pass device. Two internal compared
voltage references VTEMP-H and VTEMP-L are 80%*VCC and 45%*VCC, respectively. When the voltage at TEMP pin rises
above VTEMP-H or falls below VTEMP-L, AME2056 stops charging. After the system recover from a temperature fault, the
charger will resume operation. If applications do not need the function, short the TEMP pin to ground.
The resistance of R1 and R2 are set according to the battery temperature range and the value of thermal sensitive
resistor. Assume the battery is equipped with NTC thermistor and the temperature range is TL to TH (TL<TH). The
thermistor resistance RT decreases as temperature increases from TL to TH.
The TEMP pin voltage can be calculated as:
VTEMP =
R 2 // RT
× VCC
R1 + R 2 // RT
The VTEMP decreases as the temperature increase from TL to TH.
R1 and R2 resistance are set for temperature:
0.8 × VCC = VTEMP − H =
R 2 // RTL
× VCC
R1 + R 2 // RTL
0.45 × VCC = VTEMP− L =
R 2 // RTH
× VCC at T
H
R1 + R 2 // RTH
at TL
Where RTL and RTH are the thermistor resistances at TL and TH, respectively.
The R1 and R2 can be derived as following:
R1 =
RTL × RTH × (0.8 − 0.45)
(RTL − RTH )× 0.8 × 0.45
R2 =
RTL × RTH × (0.8 − 0.45)
RTL × (0.45 − 0.8 × 0.45) − RTH × (0.8 − 0.8 × 0.45)

AME2056
Under Voltage Lockout (UVLO)
The AME2056 incorporates an under voltage lockout circuit to keep the device disabled when VCC is below the UVLO
rising threshold voltage. Once the UVLO rising threshold voltage is reached, the device start-up begins. The device
operates until VCC falls below the UVLO falling threshold voltage. The typical hysteresis in the UVLO comparator is
200mV.
Manual Shutdown
The AME2056 can be shutdown by removing RPROG or pull the CE pin to the low-level voltage. A new charge cycle
is restarted by reconnecting the program resistor or pulling the CE pin to high-level voltage.
Automatic Recharge
After the charge cycle is terminated, the AME2056 monitors the BAT pin voltage by a comparator with a 1.8ms filter
time (TRECHARGE). When the BAT pin voltage drops below 4.1V, a charge cycle restarts. The function can keep the
battery near a fully charged condition.
Stability Considerations
In constant-current mode, the feedback loop includes the PROG pin. Because of the additional pole created by the
PROG pin capacitor and resistor. The equivalent capacitance on this pin must be kept to minimum for the maximum
allowed program resistor. The pole frequency created by the PROG pin should be kept above 100kHz. When the PROG
pin is loaded with a capacitor, CPROG, the following equation can be used to calculate the maximum resistance.
RPROG ≤
1
2 × π × 10 5 × C PROG
Generally, the average battery current may be of interest to the user rather than instantaneous current. A simple RC
filter can be used on the PROG pin to measure the average battery current as shown in Figure 1. A 10K resistor has been
added between the PROG pin and the filter capacitor to ensure stability.

Power Dissipation
AME2056 has thermal feedback protection to reduce the charging current in overload condition, so the power dissipation is required to consider. The power dissipation definition is:
PD = (VCC − VBAT ) × I BAT
Where PD is power dissipated, VCC is the input supply current, VBAT is the battery voltage and IBAT is the charge current.
AME2056 will automatically reduce the charging current to maintain the die temperature under 145oC approximately,
so it is not necessary to check maximum power dissipation. The ambient temperature of thermal feedback protection is:
T A = 145 o C − PD × θ JA = 145 o C − (VCC − V BA ) × θ JA
For example: AME2056 operating from a 5V power providing 0.8A to a 3.75V Li-Ion battery. The maximum ambient
temperature which the AME2056 operates in 0.8A condition can be calculated:
TA = 145o C − (5V − 3.75V ) × 0.8 A × 84 o C / W = 57 o C
The AME2056 can be used above 57oC, but the charging current will be reduced below 0.8A. The charging current can
be calculated:
I BAT =
145o C − TA
(VCC − VBAT ) × θ JA
According to the previous example with ambient temperature of 90oC, the charging current is reduced to:
I BAT =
145 o C − 90 o C
= 524mA
(5 − 3.75) × 84
Layout Consideratons
The good thermal conduction PCB layout is very important to apply to maximize the available charging current. The
thermal path is from the die to the PCB. The PCB is the heat sink. The copper pads footprint should be as large as
possible and expand out to large copper areas to spread and dissipate the heat to the ambient. Other heat source must
be considered when designing a PCB layout because they will affect overall temperature rise and maximum charging
current.
VCC Bypass Capacitor
Many types of capacitors can be used as input bypass capacitor. However, the high voltage transients can be
generated under some start-up conditions when using the self-resonant and high Q characteristics of ceramic capacitors.
Adding a 0.4Ω resistor in series with an X5R ceramic capacitors will minimize start-up voltage transients.
