Description
The LT4356HMS-1 is a surge stopper and overvoltage protector IC from Analog Devices. It safeguards sensitive circuits by regulating input voltage during transients, surges, or faults, clamping or limiting it to a user-set level (up to 80V).
Key features:
- Wide input range: 4V to 80V (handles surges up to 100V).
- Adjustable output clamp/limit via external resistor divider.
- Fast response (<1µs) to overvoltage events.
- Low quiescent current (100µA typical).
- Reverse input protection (-40V).
- Available in a 10-lead MSOP package.
Applications include automotive, industrial, and telecom systems where voltage spikes pose risks. The LT4356HMS-1 also includes fault reporting and can drive an external N-channel MOSFET for flexible power handling.
For detailed specs, refer to the datasheet.
