What are the key features of TPS61093-Q1?
- 1.6 V to 6 V wide input range supporting single-cell Li-Ion, alkaline, or NiMH battery sources for flexible automotive and portable power designs
- AEC-Q100 automotive qualification enabling reliable boost conversion across -40°C to +125°C in vehicle sensor modules and low-voltage interior electronics
- Integrated synchronous switches with low quiescent current in a small-outline no-lead SON package minimizing standby power and PCB footprint
What is TPS61093-Q1 used for?
The TPS61093-Q1 is designed for automotive interior lighting drivers, low-voltage sensor supply rails, and key fob battery-powered circuits requiring regulated boost output from 1.6 V to 6 V inputs. Its AEC-Q100 qualification ensures consistent switching performance during the cold-crank voltage drops and over-voltage conditions common in 12 V automotive electrical systems. The compact SON package and integrated switches reduce BOM count and board area in space-constrained vehicle interior electronics operating from primary cell or rechargeable batteries.

Frequently Asked Questions
What input voltage range does TPS61093-Q1 support and which battery chemistries can directly power it?
TPS61093-Q1 operates from 1.6 V to 6 V input, covering single-cell Li-Ion (2.7 V to 4.2 V), alkaline AA/AAA (0.9 V discharged—note single cell may go below 1.6 V near end of life), and two-cell NiMH (1.8 V to 3.0 V) batteries. For single alkaline cells requiring operation down to 0.9 V, a two-cell series configuration provides 1.8 V minimum, comfortably within the 1.6 V lower limit, supporting automotive key fob and tire-pressure sensor designs with standard battery sizes.
How does TPS61093-Q1's AEC-Q100 qualification protect boost converter performance across automotive temperature swings?
AEC-Q100 qualification subjects TPS61093-Q1 to HTOL at 125°C for 1,000 hours, THB at 85°C/85% RH, cold-soak at -40°C, and electrostatic discharge testing. These tests confirm that switching frequency, output regulation accuracy, and quiescent current remain within datasheet limits at both temperature extremes, preventing voltage dropout on 3.3 V sensor rails during winter cold-start at -40°C or during summer operation near vehicle headliner components reaching 85°C ambient.
For a compact automotive interior sensor module, how does the SON package of TPS61093-Q1 compare to a TSSOP alternative in board space?
The small-outline no-lead SON package of TPS61093-Q1 typically occupies less than 4 mm² of PCB area, versus 16 mm² to 24 mm² for an 8-pin TSSOP. This 4× to 6× reduction in footprint is critical in automotive interior sensor modules with PCBs smaller than 15 mm × 20 mm. The exposed bottom pad also improves thermal dissipation, keeping junction temperature lower than an equivalent TSSOP at the same 300 mA output current, which is important for sustained operation at 125°C ambient.
