Frequently Asked Questions
Over what temperature range does the TMP708AQDBVTQ1 operate, and how is hysteresis configured?
The TMP708AQDBVTQ1 operates from 0°C to 125°C, and hysteresis is selected by pulling a dedicated pin high or low, allowing the designer to choose between two preset hysteresis levels without external resistors, which simplifies the thermal protection circuit around battery packs and power transistors.
How does the 5-pin SOT-23 package of the TMP708AQDBVTQ1 benefit compact power-board designs?
The 5-pin SOT-23 footprint measures approximately 3 mm x 1.75 mm, occupying minimal PCB area so the temperature switch can be placed immediately adjacent to the heat-generating component being monitored, reducing thermal measurement error and enabling tighter over-temperature protection response times.
In which thermal protection applications is the TMP708AQDBVTQ1 most commonly deployed?
This device is commonly used to protect lithium-ion battery charger ICs, DC-DC converter output stages, and brushless motor drivers from thermal damage. Its 0°C to 125°C operating range and pin-selectable hysteresis make it effective in consumer electronics, industrial power supplies, and automotive accessory modules requiring reliable single-chip over-temperature shutdown.
Does the TMP708AQDBVTQ1 require external passive components to set the trip threshold?
No, the trip threshold and hysteresis are factory programmed and pin-selectable, so the TMP708AQDBVTQ1 needs no external resistors or capacitors to define the switching temperature within its 0°C to 125°C operating range, reducing BOM cost and simplifying PCB layout for high-volume production.
