Description

The LT4363IMS-2#TRPBF is a surge stopper and overvoltage protector IC from Analog Devices. It safeguards sensitive circuits by regulating input voltage during transients, surges, or overvoltage events (up to 60V).
Key features:
- Wide input range: 4V to 80V (100V transient).
- Adjustable output clamp: Limits voltage to downstream components.
- Fast response: Uses an external MOSFET for quick overvoltage shutdown.
- Current limiting: Protects against overloads with adjustable fault timer.
- Low quiescent current: ~50µA in standby.
Applications include automotive systems, industrial power supplies, and hot-swap circuits. The MSOP-10 package (IMS-2) is compact and suitable for space-constrained designs.
The -2#TRPBF variant includes tape-and-reel packaging for automated assembly.

Features

The LT4363IMS-2#TRPBF is a surge stopper designed to protect loads from high-voltage transients. Key features:
- Wide Input Range: 4V to 80V (100V absolute max).
- Adjustable Output Clamping: Limits overvoltage via external resistor.
- Fast Response: Uses a high-speed comparator to quickly disconnect the load during surges.
- Low Quiescent Current: 1.5µA in shutdown, 200µA during operation.
- Reverse Input Protection: Withstands -40V without damage.
- Adjustable Fault Timer: Prevents nuisance tripping with an external capacitor.
- Small Package: 10-lead MSOP for space-constrained designs.
Ideal for automotive, industrial, and telecom applications requiring robust overvoltage protection.

Pinout

The LT4363IMS-2#TRPBF is a 10-pin MSOP package surge stopper designed to protect loads from high-voltage transients. Key functions include:
- Overvoltage and Undervoltage Protection: Monitors input voltage via FB pin, shutting off the output if thresholds are exceeded.
- Adjustable Current Limit: Uses a sense resistor (connected to SNS and OUT pins) to limit inrush or fault currents.
- Gate Drive (GATE Pin): Controls an external N-channel MOSFET for load switching.
- Timer (TIMER Pin): Sets fault duration before latch-off (adjustable with a capacitor).
- Status Output (STAT Pin): Indicates fault conditions.
Other pins: VIN (input power), OUT (output to load), and GND (ground).
Concise and robust for transient protection in automotive/industrial apps.

Application

The LT4363IMS-2#TRPBF is a surge stopper and overvoltage protector IC. Its key application areas include:
1. Industrial Systems – Protects sensitive electronics from voltage transients.
2. Automotive – Safeguards circuits from load-dump and other surges.
3. Telecom/Networking – Ensures stable operation in harsh power environments.
4. Aviation/Aerospace – Mitigates voltage spikes in critical systems.
5. Portable Electronics – Prevents damage from faulty chargers or power sources.
It features adjustable overvoltage/undervoltage thresholds, making it versatile for various power protection needs.

Package

The LT4363IMS-2#TRPBF comes in a 10-Lead MSOP package. This surface-mount package is compact, suitable for space-constrained applications, and offers good thermal performance. The "TRPBF" suffix indicates it is supplied in tape and reel packaging for automated assembly.
