LTC1696 is a standalone power supply overvoltage monitor and protection device designed to protect a power supply load in the event of an overvoltage fault. It monitors two adjustable output voltages. If an overvoltage condition is detected, the output drives either an external SCR crowbar or turns off external back-to-back N-channel MOSFETs, thereby, disconnecting the input voltage from the power supply.
The LTC1696 (also referenced as LTG1696) is a dual‑channel overvoltage monitor designed to protect power‑supply loads. It senses two adjustable output voltages, compares them to an internal 0.88 V reference, and when an overvoltage condition is detected it can activate an external SCR crowbar or turn off back‑to‑back N‑channel MOSFETs, disconnecting the input voltage.
Key features include a low‑profile 1 mm ThinSOT package, a wide supply range of 2.7 V to 27 V, programmable glitch‑filter timing via the TIMER/RESET pin, and a multifunction timer/reset pin that also serves as an external trigger input.
| Overvoltage Threshold Accuracy | 42 % |
|---|---|

It is a standalone power‑supply overvoltage monitor and protection device that watches two adjustable output voltages and can drive an external SCR crowbar or MOSFETs to disconnect the input voltage during an overvoltage fault.
The device monitors two adjustable output voltages.
Pin 6 (TIMER/RESET) provides the programmable glitch‑filter timer, reset, and external trigger input.
The LTC1696 operates with a supply voltage from 2.7 V up to 27 V.
