Product details
Overview
TLV3501AZQDBVRQ1 from Texas Instruments is an AEC-Q100 Grade 1 qualified, 4.5-ns propagation delay, rail-to-rail input/output push-pull comparator operating from 2.7 V to 5.5 V with 6 mV internal hysteresis and shutdown control - used in HEV/EV powertrain DC-DC converters and inverter timing circuits.
For engineers reviewing the TLV3501AZQDBVRQ1 datasheet, TLV3501AZQDBVRQ1 pinout, TLV3501AZQDBVRQ1 application, or TLV3501AZQDBVRQ1 equivalent, key selection criteria include propagation delay vs. overdrive voltage, shutdown turn-on/turn-off timing, rail-to-rail common-mode range (–0.2 V to VS + 0.2 V), CMOS/TTL-compatible output drive, and automotive-grade thermal reliability (–40°C to +125°C).
Technical Context
The TLV3501AZQDBVRQ1 employs a high-speed bipolar-CMOS architecture enabling sub-5 ns propagation delay at 100 mV overdrive, with internal 6 mV hysteresis for noise immunity in noisy automotive environments. Its input stage supports common-mode voltages beyond the rails (–0.2 V to VS + 0.2 V), and its push-pull output drives CMOS or TTL logic directly without external pull-ups.
Shutdown functionality is implemented via a dedicated SHDN pin with defined thresholds: device enables when SHDN is ≤ (V+ – 1.7 V), disables when ≥ (V+ – 0.9 V); quiescent current drops to 2 µA in shutdown, with 100 ns wake-up delay and 30 ns turnoff time.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Propagation delay | 4.5 ns typical at 100 mV overdrive - enables precise timing in >80 MHz toggle applications |
| Supply voltage range | 2.7 V to 5.5 V - supports 3.3 V and 5 V automotive systems without level shifting |
| Input common-mode range | –0.2 V to VS + 0.2 V - allows direct sensing of signals below ground or above supply in battery monitoring |
| Output type | Rail-to-rail push-pull - eliminates need for external pull-up resistors and ensures fast rise/fall (1.5 ns each) |
| Internal hysteresis | 6 mV - reduces false triggering on slow/noisy inputs without external feedback components |
| Shutdown current | 2 µA - enables low-power sleep modes in always-on vehicle subsystems |
| Operating temperature | –40°C to +125°C ambient - meets AEC-Q100 Grade 1 for under-hood powertrain use |

|---|---|---|---|
| TLV3701AQDBVRQ1 | 560 nA supply current, 560 ns propagation delay, nanopower architecture | Optimized for ultra-low-power wake-up triggers, not high-speed timing | Select TLV3701AQDBVRQ1 only when propagation delay >500 ns is acceptable and standby current <1 µA is mandatory |
| TLC3702AQDRQ1 | Dual-channel, 100 µW per channel, 1.5 µs propagation delay, LinCMOS process | Targets micropower dual-threshold detection, not single-channel high-speed edge alignment | Choose TLC3702AQDRQ1 when dual comparators are needed in space-constrained modules and speed is secondary to power efficiency |
Compared with TLV3501AZQDBVRQ1, TLV3701AQDBVRQ1 trades 125× slower speed for 5700× lower quiescent current, while TLC3702AQDRQ1 offers dual functionality at 330× slower speed and higher input bias - making TLV3501AZQDBVRQ1 uniquely suited for automotive timing-critical power conversion where nanosecond accuracy is non-negotiable.

FAQ
What is the maximum toggle frequency supported by the TLV3501AZQDBVRQ1?
The TLV3501AZQDBVRQ1 supports a maximum toggle frequency of 80 MHz under test conditions of 50 mV overdrive and 5 V supply. This is derived from its 4.5 ns typical propagation delay and 1.5 ns rise/fall times, enabling reliable operation in high-frequency PWM and oscillator circuits used in automotive DC-DC converters and inverters.
Does the TLV3501AZQDBVRQ1 require external pull-up resistors on its output?
No, the TLV3501AZQDBVRQ1 does not require external pull-up resistors because it features a push-pull CMOS output stage that actively drives both high and low states. The output swings within 30–50 mV of the supply rails at ±1 mA load, ensuring direct compatibility with CMOS and TTL logic families without additional components.
How does the shutdown function operate on the TLV3501AZQDBVRQ1?
The TLV3501AZQDBVRQ1 shutdown pin (SHDN) disables the comparator when pulled to a voltage ≥ (V+ – 0.9 V), reducing quiescent current to 2 µA and placing the output in high-impedance state. It re-enables when SHDN falls ≤ (V+ – 1.7 V), with 100 ns wake-up delay and 30 ns turnoff time - critical for low-power modes in automotive always-on systems.
What is the significance of the 'Z' suffix in TLV3501AZQDBVRQ1?
The 'Z' suffix in TLV3501AZQDBVRQ1 denotes an enhanced SOT-23-6 (DBV) package with improved resistance to delamination during reflow soldering and thermal cycling. This is especially important for automotive powertrain applications where repeated thermal stress can compromise standard packages, ensuring long-term reliability in under-hood ECUs.
Can the TLV3501AZQDBVRQ1 be used with a single 3.3 V supply?
Yes, the TLV3501AZQDBVRQ1 operates fully specified from 2.7 V to 5.5 V, making it compatible with 3.3 V systems. At 3.3 V, it maintains rail-to-rail input common-mode range (–0.2 V to 3.5 V), 4.5 ns propagation delay (typical), and push-pull output swing within 50 mV of rails - ideal for interfacing with 3.3 V microcontrollers and sensors in modern EV control units.
