The MAX1600/MAX1603 power-switching ICs contain a
network of low-resistance MOSFET switches that deliver
selectable VCC and VPP voltages to two CardBus or
PC Card host sockets. The MAX1600/MAX1603 differ
only in the VY switch on-resistance. Figure 1 is the
detailed block diagram.
The power-input pins (VY, VX, 12IN_) are completely
independent. Low inrush current is guaranteed by con-
trolled switch rise times. VCC’s 100µs minimum output
rise time is 100% tested with a 1µF capacitive load, and
VPP’s 1ms minimum rise time is guaranteed with a 0.1µF
load. These respective capacitive loads are chosen as
worst-case card-insertion parameters. The internal
switching control allows VCC and VPP rise times to be
