Figure 24. Logic Connections to CL-PD6720
Intel’s 82365SLDF controller uses active-high control logic for V
CC
selection, which requires connecting the
82365SLDF’s 3-V control outputs (A_VCC_EN0, B_VCCEN0) to the TPS2201’s 5-V control inputs (A_VCC5,
B_VCC5) and the 5-V control outputs (AVCC_EN1, B_VCC_EN1) to the 3-V control inputs (A_VCC3, B_VCC3),
as illustrated in Figure 25. Examination of the control logic tables on page 16 will confirm that these connections
will in fact select the correct output voltage. An alternative approach would be to invert the Intel V
CC
control logic
signals before routing them to the TPS2201.
The separate V
pp
power-good indicators of the TPS2201 can be connected directly to the Intel controller as
shown in Figure 25.
Cirrus Logic defines a (1, 1) on the V
CC
select lines to be the PC Card no connect state; Intel chose (0, 0) to
select this state. As the tables show, either combination switches the V
CC
outputs to 0 V. The decision to provide
0 V versus a high impedance for the no connect state eliminates potential charging at the switch-to-card
interface. Feedback from the PC Card design community favors this approach.
V
pp
logic allows for 0-V or high-impedance output for no connect (0, 0) or reserved (1, 1) logic inputs, respectively
(refer to AVPP and BVPP control-logic tables on page 16). Both the Cirrus Logic and Intel controllers interface
directly with the V
pp
control inputs of the TPS2201.
The shutdown input of the TPS2201, SHDN, when held at a logic low places all V
CC
and V
pp
outputs in a
high-impedance state and reduces chip quiescent current to 1
μ
A to conserve battery power.
An overcurrent output (OC) is provided to indicate an overcurrent condition in any of the V
CC
or V
pp
supplies
(see discussion above).
ESD protection
All TPS2201 inputs and outputs incorporate ESD-protection circuitry designed to withstand a 2-kV
human-body-model discharge as defined in MIL-STD-883C. The V
CC
and V
pp
outputs can be exposed to
potentially higher discharges from the external environment through the PC card connector. Bypassing the
outputs with 0.1-
μ
F capacitors protects the devices from discharges up to 10 kV.
