Figure 1. Detailed Block Diagram
_______________Detailed Description
The MAX1602 power-switching IC contains a network of
low-resistance MOSFET switches that deliver selectable
VCC and VPP voltages to two CardBus or PC Card host
socket. Figure 1 is the detailed block diagram.
The power-input pins (VY, VX, 12IN) are completely
independent, however, power must always be applied
to VY for proper operation. Low inrush current is guaran-
teed by controlled switch rise times. VCC’s 100µs mini-
mum 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 capaci-
tive loads are chosen as worst-case card-insertion para-
meters. The internal switching control allows VCC and
VPP rise times to be controlled, and makes them nearly
