Dual-Channel CardBus PCMCIA VCC/VPP Power-Switching Networks
MAX1600/MAX1603 power-switching contain network low-resistance MOSFET switches that deliver selectable voltages CardBus Card host sockets. features include ultra-low-resistance switches, small packaging, softswitching action, compliance with PCMCIA specifications 3V/5V switching. 3.3V-only power switching fast, 32-bit CardBus applications supported ways: stiff, low-resistance 3.3V switches allow high 3.3V load currents 1A); completely independent internal charge pumps 3.3V switch operate normally, even +12V supplies disconnected turned conserve power. internal charge pumps regulating types that draw reduced input current when switches static. Also, power consumption automatically reduced 10µA when control logic inputs programmed high-Z states, unlike other solutions that require separate shutdown-control input. Other features include guaranteed specifications output current limit level, guaranteed specifications output rise/fall times compliance with PCMCIA specifications). Reliability enhanced thermal-overload protection, accurate current limiting, overcurrent-fault flag output, undervoltage lockout. CMOS/TTL-logic interface flexible, tolerate logic input levels excess positive supply rail. MAX1600 MAX1603 identical, except MAX1603's switch on-resistance (typically 160m).

controlled, makes them nearly independent resistive capacitive loads (see rise-time photos Typical Operating Characteristics Fall times function loading, compensated internal circuitry. Power savings automatic: internal charge pumps draw very current when switches static. Standby mode reduces switch supply current 1µA. Driving with external logic gate (master shutdown) reduces total supply current to1µA (Figure
Overcurrent Protection
Peak detecting circuitry protects both switches against overcurrent conditions. When current through switch exceeds internal current limit switches 200mA switches) switch turns briefly, then turns again controlled rise rate. overcurrent condition lasts more than 2µs, FAULT output goes low. FAULT latched. continuous short-circuit condition results pulsed output current pulsed FAULT output until thermal shutdown reached. FAULT open-drain requires external pull-up resistor.
Operating Modes
MAX1600/MAX1603 compatible with Cirrus CL-PD67XX, Databook DB86184, Intel 82365SL Card Interface Controllers (PCIC). Eight control inputs select internal switches' positions operating modes according input code. Select proper code format chosen controller with CODE input (see Description Tables CODE reconfigures logic decoder three interface controllers: Standard "Intel" code (Figure High "Cirrus" code (Figure Midsupply "Databook" code (Figure additional (3µA max) supply current will flow CODE midsupply MAX1600/MAX1603 have three operating modes: normal, standby, shutdown. Normal mode supplies selected outputs with their appropriate supply voltages. Standby mode places switches ground, high impedance, combination two. Shutdown mode turns switches off, puts outputs into high-impedance state. Pull enter shutdown mode. ensure 0.05V/µs fall rate series resistor 0.1µF capacitor ground (Figure
Thermal Shutdown

Undervoltage Lockout

When voltage initially applied 12IN_, must greater than allow switch operate. Operation continues until voltage falls below (the output high impedance).
