LTC4367IMS8#PBF Overvoltage Protection Controller | 2.5V to 60V 8-MSOP
Ensure bulletproof circuit protection with the LTC4367IMS8#PBF, a high-performance overvoltage / undervoltage protection controller from Analog Devices designed for industrial, automotive, and portable electronics. This 8-MSOP PMIC safeguards sensitive components against voltage surges (up to 100V), reverse polarity, and AC transients while consuming just 70µA in operation — the right combination of headroom and quiescent power for always-on protection on a wide range of supply rails.
Designed for the realities of harsh deployment, the LTC4367 covers a wide 2.5V to 60V input range for compatibility with 12V/24V automotive systems and industrial power supplies, fast 500µs recovery (LTC4367-1 variant) to minimise downtime in network equipment and automation controls, and adjustable OV/UV thresholds via external resistors for flexible design integration.
Ultra-Low Power (70µA) with Adjustable OV/UV Thresholds & Fast Recovery
- Wide input range (2.5V-60V) — ideal for 12V/24V automotive systems and industrial power supplies.
- Fast 500µs recovery (LTC4367-1) — minimises downtime in network equipment and automation controls.
- Adjustable thresholds — customise OV/UV trip points via external resistors for flexible integration.
- Fault indication output — instant alerts for shutdowns or voltage faults, enhancing system diagnostics.
- Surge tolerance -40V to +100V — survives load-dump and transient events without damage.
Where the LTC4367 Fits
Trusted by engineers for load-dump protection, battery-powered devices, and harsh-environment electronics, this original LTC4367 chip delivers robust, reliable performance in a compact 8-pin MSOP package. Common applications: protecting downstream microcontrollers from automotive transients, gating sensitive analog blocks against supply faults, and providing fault-flag outputs to system controllers that need to log power-rail events for diagnostics. Operates from -40°C to +85°C (90°C peak) — wide enough for most industrial deployments.
