Key Features
- Integrated voltage reference eliminates external reference components, reducing BOM cost and board area in threshold detection circuits
- Push-pull output swings rail-to-rail without external pull-up resistor, directly driving logic inputs at 3.3 V or 5 V supply
- Ultra-miniature 4-pin DSBGA package (1 mm x 1 mm) enables space-constrained wearable and IoT sensor designs
Applications
The TLV4041R1YKAR is well-suited for battery level detection, over-voltage protection, and threshold monitoring in portable IoT and wearable devices requiring a tiny footprint. Its push-pull output directly interfaces with microcontroller GPIO pins without additional pull-up components, simplifying design. The -40°C to 125°C operating range makes it suitable for automotive and industrial sensor applications where compact size and reliability are critical.

Frequently Asked Questions
What is the maximum input offset voltage of the TLV4041R1YKAR, and how does it affect threshold accuracy in battery detection?
The TLV4041R1YKAR has a maximum input offset voltage of 4000 µV (4 mV). In a battery level detection circuit set to trip at 3.0 V, this offset introduces up to ±4 mV error in the trigger threshold. For most battery monitoring applications this is acceptable, but designers requiring tighter accuracy below 2 mV offset should consider higher-precision comparator variants.
How does the integrated reference in the TLV4041R1YKAR simplify a low-battery warning circuit for a coin-cell device?
The built-in reference voltage eliminates the need for an external resistor divider or reference IC, saving at least 2 passive components on a coin-cell powered PCB. The push-pull output directly drives a microcontroller interrupt pin with no pull-up resistor. Combined with its 0.005 µA maximum bias current, the total quiescent current impact on a 20 mAh coin cell is negligible over a multi-year lifetime.
What is the package size of the TLV4041R1YKAR, and what PCB land pattern clearances are needed for assembly?
The TLV4041R1YKAR uses a 4-bump DSBGA package measuring approximately 1.0 mm x 1.0 mm with a 0.5 mm bump pitch. The body occupies under 1 mm² of board area, making it one of the smallest comparator packages available. IPC-7351 guidelines for this DSBGA recommend solder mask openings of approximately 0.25 mm diameter, requiring fine-pitch PCB fabrication capability.
Over what temperature range does the TLV4041R1YKAR operate, and which automotive or industrial tiers does it cover?
The TLV4041R1YKAR is specified for -40°C to 125°C junction temperature, covering automotive Grade 1 and industrial extended-temperature requirements. This range accommodates under-hood automotive sensor nodes and outdoor industrial equipment experiencing wide ambient swings. The part is AEC-Q100 qualified and RoHS compliant with the NOPB lead-free designation.
