What this dual high-side driver is for
The LTC1155CS8#PBF from Analog Devices is a dual high-side gate driver built for N-channel MOSFETs. It handles two independent loads from a single 8-pin SOIC, with a supply range of 4.5V to 18V that covers both 5V logic rails and 12V automotive-style buses. The non-inverting inputs and independent channel control let you switch two loads — say, a solenoid and a fan — without extra level-shifting or cross-conduction worries.
Supply voltage and logic thresholds — what fits
The 4.5V to 18V supply range means this driver works directly off a 5V rail or a 12V battery line. Logic thresholds are 0.8V low and 2V high, so it's compatible with 3.3V or 5V logic without extra translation. If your design runs on a 3.3V-only rail, the LTC1157CS8#PBF (3.3V supply) is the better fit.
Temperature grade — indoor only
Rated 0°C to 70°C, this is a commercial-temperature part. Fine for office equipment, appliances, or indoor industrial panels. For outdoor, under-hood, or freezer environments, the LTC1155IS8#PBF extends the range to -40°C to 85°C.
