Texas Instruments TLV4041R5DBVR

Overview

TLV4041R5DBVR from Texas Instruments is a precision, low-power comparator with integrated 0.5 V reference, non-inverting input, and push-pull output. It operates from 1.6 V to 5.5 V, draws only 2 µA quiescent current, delivers 360 ns propagation delay, and supports –40°C to +125°C operation - ideal for lithium-ion battery voltage monitoring in portable power management systems.

For engineers reviewing the TLV4041R5DBVR datasheet, TLV4041R5DBVR pinout, TLV4041R5DBVR application, or TLV4041R5DBVR equivalent, key selection criteria include its factory-trimmed 0.5 V threshold (±0.5% at 25°C, ±1% over temperature), precision hysteresis (20 mV), rail-to-rail input stage, known power-on reset behavior, and SOT-23-5 package compatibility with space-constrained PCB layouts.

Technical Context

The TLV4041R5DBVR implements a rail-to-rail input comparator core with internal 0.5 V precision reference, non-inverting topology, and push-pull output stage. Its dual-threshold architecture provides fixed VIT+ = 0.495–0.505 V and VIT− = 0.4752–0.4848 V at 25°C, enabling reliable undervoltage/overvoltage detection without external resistors.

Power-on reset (POR) forces output low during supply ramp-up until VS ≥ 1.45 V, ensuring deterministic startup. Input bias current is ≤10 pA, and output swing is specified to within 100 mV of rails at 200 µA load - critical for interfacing directly with low-voltage logic or microcontroller GPIOs.

FAQ

What is the exact reference voltage tolerance of TLV4041R5DBVR over temperature?

The TLV4041R5DBVR features a factory-trimmed 0.5 V reference with ±0.5% accuracy at 25°C and ±1% accuracy over the full –40°C to +125°C operating range. This is confirmed in Section 6.5 Electrical Characteristics of the official datasheet (SNVSB04C), where VIT+ is specified as 0.495–0.505 V at 25°C and 0.49–0.51 V across temperature - enabling precise, calibration-free voltage detection in battery and power management systems using TLV4041R5DBVR.

Does TLV4041R5DBVR require external hysteresis components?

No, TLV4041R5DBVR integrates 20 mV of precision hysteresis internally, eliminating the need for external resistors or capacitors. This is explicitly stated in the Features section and verified in Table 6-5 (Electrical Characteristics), where VHYS is listed as 20 mV at 25°C. The hysteresis remains stable across temperature and supply voltage, making TLV4041R5DBVR suitable for noise-prone environments like motor drives or automotive cabins without additional circuitry.

What is the power-on reset (POR) behavior of TLV4041R5DBVR?

The TLV4041R5DBVR asserts its output low during power-up until the supply voltage (V+) reaches ≥1.45 V, after which normal comparator operation begins. This POR behavior is documented in Section 6.5 (VPOR = 1.45 V) and Section 8.4.1, and applies specifically to push-pull variants like TLV4041R5DBVR. It ensures deterministic startup in battery-powered systems where supply ramps slowly, preventing spurious outputs that could trigger false faults before stable operation is achieved using TLV4041R5DBVR.

Can TLV4041R5DBVR interface directly with a 1.8 V microcontroller GPIO?

Yes, TLV4041R5DBVR's push-pull output swings within 100 mV of V− (ground) and V+ (supply) at 200 µA load, so when powered from 1.8 V, it delivers VOH ≥1.7 V and VOL ≤100 mV - fully compatible with standard 1.8 V CMOS logic thresholds. This is verified in Section 6.5 (VOH/VOL specs) and eliminates need for level-shifting buffers, simplifying interconnect in low-voltage IoT sensor nodes using TLV4041R5DBVR.

Is TLV4041R5DBVR available in both SOT-23 and DSBGA packages?

No - TLV4041R5DBVR is exclusively offered in the SOT-23-5 (DBV) package, as confirmed in the "Device Information" table and orderable addendum of the datasheet. While the broader TLV40x1 family includes DSBGA variants (e.g., TLV4041R5YKAR), the DBVR suffix denotes the SOT-23-5 variant only. Engineers selecting TLV4041R5DBVR must use the 2.9 mm × 1.6 mm SOT-23 footprint, not the 0.73 mm × 0.73 mm DSBGA.
