MAX1602EEE+T

Overview

The MAX1602EEE+T is a single-channel CardBus and PCMCIA power-switching integrated circuit manufactured by Analog Devices Inc./Maxim Integrated. It delivers selectable VCC and VPP voltages to a single host socket using low-resistance MOSFET switches. The device operates within a supply voltage range of 3V to 5.5V and supports a maximum supply current of 20µA. It features independent internal charge pumps, ensuring low RDS(ON) switching without requiring 5V or 12V auxiliary supplies. The component is housed in a 16-pin QSOP package and functions within an operating temperature range of -40°C to +85°C.

Feature Summary

• Supports a single PC Card or CardBus socket with selectable VCC and VPP outputs
• Integrates low-resistance MOSFET switches for efficient power delivery
• Includes soft-switching action to minimize inrush surge currents during activation
• Provides overcurrent protection and thermal shutdown capabilities

Applications

• Data loggers requiring portable power management
• Handy-terminals utilizing PCMCIA expansion slots
• Docking stations managing peripheral power distribution
• PCMCIA read/write drive systems

Procurement Notes

Verify the specific suffix 'EEE+T' against the manufacturer's official datasheet to confirm the tape-and-reel packaging configuration. Ensure compatibility with the 16-QSOP footprint and validate that the component meets RoHS standards required for your assembly process. Cross-reference the part number with the latest Analog Devices inventory status, as availability may vary by region.

Selection Notes

Select this component when designing systems requiring compliant power switching for a single PCMCIA or CardBus socket. It is suitable for applications needing low standby current and protection against overcurrent conditions. Consider the 16-QSOP package size constraints and the requirement for 3V to 5.5V logic levels. This IC eliminates the need for external high-voltage generators due to its internal charge pumps.

Part Context

This device belongs to the Maxim Integrated power management family, specifically designed for mobile computing peripherals. It replaces discrete switch networks with a compact, code-compatible solution. The MAX1602 series adheres to industry-standard coding compatible with Intel 82365SL controllers, facilitating integration into legacy and modern PCMCIA host architectures.

Replacement Considerations

The MAX1602EEE is noted as obsolete. Verify if the MAX1602EEE+T serves as the direct active replacement. Check for code compatibility with Cirrus CL-PD67XX family devices if substituting in existing designs.
