Product details
Overview
TPS3760AE95DYYRQ1 from Texas Instruments is an AEC-Q100 Grade 1 automotive high-voltage supervisor IC with undervoltage detection, 30V threshold, 5% hysteresis, open-drain active-low reset output, and no latch function. It operates from 2.7V to 65V supply, draws 1µA typical quiescent current, and supports programmable sense (CTS) and reset (CTR) delays for robust battery rail monitoring in harsh automotive environments.
For engineers reviewing the TPS3760AE95DYYRQ1 datasheet, TPS3760AE95DYYRQ1 pinout, TPS3760AE95DYYRQ1 application, or TPS3760AE95DYYRQ1 equivalent, this device delivers precise 30V undervoltage supervision with 5% hysteresis, 65V-rated SENSE/RESET pins, and capacitor-programmable timing-critical for telematics, head unit, and body control module power integrity validation.
Technical Context
The TPS3760AE95DYYRQ1 implements a single-channel undervoltage (UV) detection architecture with fixed internal voltage divider, enabling direct connection to 12V/24V automotive battery rails without external resistors. Its SENSE pin compares monitored voltage against a 30V threshold with 5% hysteresis (±1.5V), while VDD and SENSE operate independently-allowing VDD to be powered from a lower-voltage domain.
Timing is controlled via two external capacitors: CTS sets sense delay (1.28ms–1.28s range), and CTR sets reset release delay (12.8ms–12.8s range). The open-drain RESET output requires an external pull-up and asserts low on UV fault, deasserting only after CTR delay once SENSE recovers beyond 30V + hysteresis.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | 2.7V to 65V - enables direct connection to automotive battery without level-shifting or regulation |
| Voltage Threshold | 30V undervoltage - triggers reset when monitored rail drops below 30V ±1.5V (5% hysteresis) |
| Quiescent Current | 1µA typical - minimizes parasitic drain on always-on battery circuits over vehicle lifetime |
| SENSE/RESET Pin Rating | 65V continuous - supports direct monitoring of high-side battery rails without external clamping |
| Sense Delay Range | 1.28ms to 1.28s (via 10nF–10µF CTS) - rejects cold-crank transients and start-stop voltage dips |
| Reset Release Delay | 12.8ms to 12.8s (via 10nF–10µF CTR) - prevents premature MCU wake-up during slow battery recovery |
| Output Topology | Open-drain, active-low - compatible with standard 3.3V/5V logic pull-ups and multi-source reset buses |
Pinout & Package
TPS3760AE95DYYRQ1 is housed in a 14-pin SOT-23 (DYY) package measuring 4.1mm × 1.9mm, optimized for space-constrained automotive PCBs. All GND pins (8, 13) must be connected to system ground; NC pins (2, 4, 5, 7, 11, 12, 14) are internally unconnected and must remain floating.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| VDD (Pin 1) | Power input | Bypassed with 0.1µF capacitor to GND; powers internal circuitry independently of SENSE voltage |
| SENSE (Pin 3) | Voltage monitor input | High-impedance node comparing 30V threshold; accepts up to 65V; supports external resistor divider if needed |
| RESET (Pin 6) | Reset output | Open-drain, active-low; requires external pull-up; asserts low during undervoltage fault |
| CTS (Pin 10) | Sense delay capacitor | Connects to ground-referenced capacitor to set UV detection delay (1.28ms–1.28s) |
| CTR/MR (Pin 9) | Reset delay & manual reset | Capacitor sets reset release time; driven low forces immediate reset assertion |
| GND (Pins 8, 13) | Ground reference | Both pins must be electrically tied to PCB ground plane for thermal and noise performance |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q100 Grade 1 qualification | Validated for –40°C to +125°C ambient operation-meets automotive reliability and lifetime requirements |
| Functional Safety Capability | Documentation available to support ISO 26262 ASIL-B system-level safety analysis and FMEDA |
| 65V-rated SENSE and RESET pins | Eliminates need for external TVS or clamping diodes when monitoring 24V/48V battery systems |
| Programmable hysteresis options | 5% hysteresis (±1.5V at 30V) prevents chatter during noisy battery transients like load dump |
| No external resistor required | Integrated precision voltage divider enables 30V UV detection without external components or leakage error |
| Manual Reset (MR) support | Pin 9 doubles as MR input-driving it low forces immediate reset, enabling software-controlled system recovery |
Applications

Equivalent & Alternatives
The following parts are listed as comparable options for similar undervoltage supervision applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TPS3760AE95DSKRQ1 | Same 30V UV threshold, 5% hysteresis, and open-drain output-but in 10-pin WSON (2.5mm × 2.5mm) package | Preferred for ultra-dense layouts where footprint area is constrained more than height or thermal mass | Select DSKRQ1 for space-critical modules; DYYRQ1 for better thermal dissipation and legacy SOT-23 compatibility |
| TPS3760E312DYYRQ1 | 3.1V overvoltage (OV) detection instead of 30V UV; same SOT-23 package, open-drain output, no latch | Used for protecting downstream 3.3V logic from overvoltage faults-not interchangeable for battery rail supervision | Choose only if application requires OV detection on low-voltage rails; not a functional substitute for 30V UV monitoring |
Compared with TPS3760AE95DSKRQ1, the DYYRQ1 offers superior thermal resistance (131.5°C/W vs. 87.4°C/W) and established SMT handling, while TPS3760E312DYYRQ1 serves a fundamentally different overvoltage protection role-making DYYRQ1 the sole drop-in alternative for 30V automotive battery supervision.

FAQ
What is the exact undervoltage threshold and hysteresis of TPS3760AE95DYYRQ1?
The TPS3760AE95DYYRQ1 has a fixed 30V undervoltage threshold with ±1.5V (5%) hysteresis, meaning it asserts reset when SENSE drops below 30V and releases reset only after SENSE rises above 31.5V. This specification is guaranteed across –40°C to +125°C ambient temperature per AEC-Q100 Grade 1 testing.
Does TPS3760AE95DYYRQ1 require external resistors to set its 30V threshold?
No, TPS3760AE95DYYRQ1 integrates a precision internal voltage divider optimized for 30V undervoltage detection, eliminating external resistors and associated leakage current errors. External resistors are optional only if custom thresholds are needed-though not applicable to this fixed 30V variant.
Can TPS3760AE95DYYRQ1 monitor voltages higher than its VDD supply?
Yes, TPS3760AE95DYYRQ1 supports independent VDD and SENSE voltage domains: VDD may be supplied from a low-voltage domain (e.g., 3.3V) while SENSE monitors up to 65V battery rails. This enables flexible power architecture design without level-shifting circuitry.
What is the function of the CTS and CTR pins on TPS3760AE95DYYRQ1?
CTS (Pin 10) sets the sense delay time-connecting a capacitor to ground configures UV detection delay from 1.28ms to 1.28s. CTR/MR (Pin 9) sets reset release delay (12.8ms–12.8s) and doubles as manual reset: driving it low forces immediate RESET assertion regardless of SENSE state.
Is TPS3760AE95DYYRQ1 qualified for automotive safety-critical systems?
Yes, TPS3760AE95DYYRQ1 is Functional Safety-Capable with documentation available to support ISO 26262 ASIL-B system-level safety analysis. It meets AEC-Q100 Grade 1 requirements (–40°C to +125°C), HBM ESD Level 2, and CDM Level C7B-enabling use in telematics, cluster, and body control modules.
