THEORY OF OPERATION
The ADP3510 is a total solution power management chip for use
with CDMA baseband chipsets and is optimized for the CBP3.0/
4.0 type chipsets. Figure 1 shows a block diagram of the ADP3510.
The ADP3510 contains several blocks:
∑
Six Low Dropout Regulators (Input-Output, Core, Analog,
Crystal Oscillator, Memory, Realtime Clock)
∑
Reset Generator
∑
Buffered Precision Reference
∑
Lithium Ion Charge Controller and Processor Interface
∑
Power-On/-Off Logic
∑
Undervoltage Lockout
∑
Deep Discharge Lockout
These functions have traditionally been done either as a discrete
implementation or as a custom ASIC design. The ADP3510
combines the benefits of both worlds by providing an integrated
standard product where every block is optimized to operate in a
CDMA environment while maintaining a cost-competitive solution.
Figure 3 shows the external circuitry associated with the ADP3510.
Only a minimal number of support components are required.
Input Voltage
The input voltage range of the ADP3510 is 3.2 V to 7.5 V and is
optimized for a single Li-Ion cell or three NiMH cells. The thermal
impedance of the ADP3510 is 68
∞
C/W for four layer boards. The
end of charge voltage for high capacity NiMH cells can be as high
as 5.5 V. Power dissipation should be calculated at maximum ambi-
ent temperatures and battery voltage in order not to exceed the 125
∞
C
maximum allowable junction temperature. Figure 4 shows the maxi-
mum power dissipation as a function of ambient temperature.
