Analog Devices Inc./Maxim Integrated MAX4513CPE

Overview

The MAX4513CPE from Maxim Integrated is a quad SPST analog switch with two normally closed (NC) and two normally open (NO) channels, fault-protected up to ±36V with power applied and ±40V with power off, rail-to-rail signal handling (±15V dual or +9V–+36V single supply), 175Ω max on-resistance, and TTL/CMOS-compatible logic inputs - used in industrial data acquisition systems requiring robust signal routing under overvoltage transients.

For engineers reviewing the MAX4513CPE datasheet, MAX4513CPE pinout, MAX4513CPE application, or MAX4513CPE equivalent, key selection criteria include fault-protection voltage range, COM output current capability during fault (±10mA), break-before-make timing (50–100ns for MAX4513 only), on-resistance matching (≤10Ω), and compatibility with legacy DG201/DG202/DG213 layouts.

Technical Context

The MAX4513CPE implements dual-FET parallel switching architecture (N- and P-channel) per channel, enabling low on-resistance while maintaining rail-to-rail conduction. Fault detection uses dedicated comparators monitoring NO_/NC_ pins against V+ and V−; during overvoltage, internal FETs isolate the protected terminal and activate booster FETs to clamp COM_ to the appropriate supply rail.

It supports asymmetric dual supplies (e.g., +15V/−5V) within ±4.5V to ±18V total range or single +9V to +36V operation with V− tied to GND. Logic thresholds (0.8V low / 2.4V high at ±15V) remain functional across supply voltages, and no power-supply sequencing is required - critical for hot-swap and brownout resilience in avionics and process-control systems.

Key Specifications

FAQ

What is the maximum fault voltage the MAX4513CPE can withstand with power applied?

The MAX4513CPE withstands ±36V on its NC_ and NO_ pins when power is applied to V+ and V−. This rating applies across the full operating temperature range and is validated per Absolute Maximum Ratings. Exceeding ±36V risks permanent damage, even briefly. The device also supports ±40V fault tolerance with power removed - critical for maintenance safety.

Does the MAX4513CPE require power-supply sequencing during startup?

No, the MAX4513CPE does not require power-supply sequencing. V+ and V− may be powered in any order, and the device remains functional and fault-protected throughout power-up transients. This eliminates need for external sequencers in multi-rail systems and enhances reliability during brownout conditions - a key advantage over many competing analog switches.

Can the COM_ pins of the MAX4513CPE be overvolted safely?

No, the COM_ pins of the MAX4513CPE are not fault-protected. Signals on COM_ must remain strictly within the V− to V+ range. Exceeding these limits forward-biases internal ESD diodes, causing high current flow that may damage the device. Only NC_ and NO_ pins have ±36V fault protection - proper system-level design must constrain COM_ voltage accordingly.

What is the purpose of the break-before-make timing in the MAX4513CPE?

The MAX4513CPE incorporates 50–100ns break-before-make delay specifically on its mixed NC/NO channels (pins 1/4 and 2/3) to prevent momentary shorting during state transitions. This ensures clean signal path switching in redundant architectures - for example, avoiding brief cross-conduction when selecting between primary and backup sensor inputs in safety-critical systems.

Is the MAX4513CPE pin-compatible with older industry-standard switches?

Yes, the MAX4513CPE has identical pinout to the DG201/DG202/DG213 and DG411/DG412/DG413 families. Its 16-pin DIP layout allows direct socket replacement in existing PCBs. However, designers must verify that only NC_/NO_ pins (not COM_ or IN_) require fault protection in their application - the underlying protection architecture differs, though mechanical and electrical pin mapping is preserved.
