This makes it a drop-in guard for thermal runaway or cold-start lockout on a PCB — no programming, no external resistor dividers to set the trip point. Accuracy is specified at ±2°C, which is tight enough for equipment-level thermal protection — a server PSU or battery-charger board that must flag overtemperature before the silicon hits its abs-max junction rating. ## Supply rails and output drive The open-drain outputs sink 0.2 mA, enough to pull a microcontroller GPIO low through a 10 kΩ pull-up. Both an active-high and active-low output are available — /OverTemp and /UnderTemp — so the same part can drive a reset line (active-low) or light an indicator (active-high) without an external inverter.","metaTitle":"LTC2996CDD#PBF Temp Sensor, ±2°C, Active High/Low Output","metaDescription":"LTC2996CDD#PBF temperature sensor from Analog Devices. ±2°C accuracy, active high/low open-drain outputs, fixed -20°C/70°C thresholds.
