Product details
Overview
TPS3760E335DYYRQ1 from Texas Instruments is an AEC-Q100 Grade 1 automotive-grade high-voltage supervisor IC with overvoltage (OV) detection at 3.3 V ±1.5%, 5% hysteresis, open-drain active-low RESET output, and 1 µA typical quiescent current. It operates from 2.7 V to 65 V supply, supports independent SENSE pin monitoring up to 65 V, and targets battery-supplied automotive subsystems requiring robust voltage supervision under cold-crank and start-stop transients.
For engineers reviewing the TPS3760E335DYYRQ1 datasheet, TPS3760E335DYYRQ1 pinout, TPS3760E335DYYRQ1 application, or TPS3760E335DYYRQ1 equivalent, key selection considerations include its OV-only 3.3 V threshold with 5% hysteresis, programmable sense/reset delays via external capacitors, manual reset capability, and SOT-23-14 (DYY) package compatibility with automotive thermal and layout constraints.
Technical Context
The TPS3760E335DYYRQ1 implements a precision comparator-based OV detection architecture with internal 3.3 V reference and fixed resistor divider, enabling direct connection to 12 V/24 V battery rails without external resistors. Its SENSE and RESET pins are rated for continuous 65 V operation, decoupling monitoring voltage from VDD supply level.
Timing control is achieved via two dedicated capacitor-programmable pins: CTS sets sense delay (1.28 ms to 1.28 s), and CTR sets reset release delay (12.8 ms to 12.8 s); both use internal 100 kΩ and 1 MΩ timing resistors respectively. The device lacks latch functionality and uses open-drain output requiring external pull-up.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | 2.7 V to 65 V - enables direct connection to automotive battery without pre-regulation |
| Detection Threshold | 3.3 V OV ±1.5% - precise overvoltage trip point for 3.3 V rail supervision |
| Hysteresis | 5% - rejects noise and transient dips during engine cranking or load dump |
| Quiescent Current | 1 µA typical - minimizes standby power draw in always-on vehicle modules |
| SENSE Pin Rating | 65 V continuous - allows monitoring of higher-voltage rails independent of VDD |
| Output Type | Open-drain active-low - supports flexible logic-level translation and wired-OR configurations |
| Sense Delay Range | 1.28 ms to 1.28 s (via CTS capacitor) - configurable immunity to short-duration voltage spikes |
| Reset Delay Range | 12.8 ms to 12.8 s (via CTR capacitor) - ensures system stability before releasing reset |
Pinout & Package
TPS3760E335DYYRQ1 is packaged in a 14-pin SOT-23 (DYY) with 4.1 mm × 1.9 mm body size, optimized for space-constrained automotive PCB layouts and qualified for –40°C to +125°C ambient operation.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| VDD (Pin 1) | Power Supply Input | Bypassed with 0.1 µF capacitor to GND; supplies internal circuitry independently of SENSE voltage |
| SENSE (Pin 3) | Voltage Monitoring Input | Compares monitored rail to 3.3 V OV threshold; 65 V rated, high-impedance input for minimal loading |
| RESET (Pin 6) | Active-Low Reset Output | Open-drain output requiring external pull-up; asserts low on OV condition after CTS delay |
| CTS (Pin 10) | Sense Time Delay Control | Connects to ground-referenced capacitor to set OV detection assertion delay (1.28 ms–1.28 s) |
| CTR/MR (Pin 9) | Reset Release Delay & Manual Reset | Capacitor sets reset deassertion delay; driven low forces immediate reset assertion |
| GND (Pins 8, 13) | Ground Reference | Both pins must be connected to system ground for proper operation and thermal performance |
| NC (Pins 2,4,5,7,11,12,14) | No Connect | Internally unconnected; must remain floating per datasheet |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q100 Grade 1 qualification | Validated for –40°C to +125°C ambient operation in automotive environments |
| 65 V SENSE and RESET pin rating | Enables direct monitoring of 12 V/24 V battery without external clamping or level-shifting |
| Programmable OV sense delay (CTS) | Configurable immunity to <1.28 ms transients using standard ceramic capacitors |
| Programmable reset release delay (CTR) | Ensures MCU or processor completes boot sequence before reset release |
| Manual reset (MR) input | Allows system-level forced reset initiation independent of SENSE voltage state |
| Internal 3.3 V voltage divider | Eliminates external resistor network, reducing BOM count and leakage current |
Applications

Equivalent & Alternatives
The following parts are listed as comparable options for similar overvoltage supervisor applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TPS3760E312DYYRQ1 | 3.1 V OV threshold, 2% hysteresis, same SOT-23-14 package and timing architecture | Lower trip point suits 3.1 V rails; reduced hysteresis offers tighter window but less noise immunity | Select when 3.1 V OV detection with faster recovery is required; verify system margin against 3.1 V tolerance |
| TPS3760BF05DYYRQ1 | 31 V OV threshold, 5% hysteresis, push-pull active-low output instead of open-drain | Targets high-voltage rail supervision; eliminates need for external pull-up resistor | Choose for 31 V battery or DC-DC output monitoring where board space or BOM simplification is critical |
Compared with TPS3760E335DYYRQ1, TPS3760E312DYYRQ1 provides lower OV threshold and reduced hysteresis for tighter regulation, while TPS3760BF05DYYRQ1 shifts to high-voltage monitoring with push-pull output-neither offers pin-to-pin compatibility, requiring schematic and layout review for substitution.

FAQ
What is the exact overvoltage threshold voltage of the TPS3760E335DYYRQ1?
The TPS3760E335DYYRQ1 has a nominal overvoltage threshold of 3.3 V with ±1.5% accuracy across –40°C to +125°C ambient temperature. This value is factory-trimmed and specified in the Electrical Characteristics table under VITP parameter for overvoltage detection. The part number suffix "E335" explicitly denotes the 3.3 V OV variant with 5% hysteresis.
Does the TPS3760E335DYYRQ1 support undervoltage detection?
No, the TPS3760E335DYYRQ1 is configured exclusively for overvoltage (OV) detection. Per Table 4-1 in the datasheet, its "Sense logic" is labeled "OV", and it does not monitor undervoltage conditions. For combined OV/UV supervision, TI recommends the TPS3762-Q1 or TPS37-Q1 families instead of the TPS3760E335DYYRQ1.
What package type does the TPS3760E335DYYRQ1 use, and what are its dimensions?
The TPS3760E335DYYRQ1 uses the SOT-23-14 (DYY) package with nominal body dimensions of 4.1 mm × 1.9 mm. This surface-mount package is specified in the Mechanical, Packaging, and Orderable Information section and is distinct from the WSON-10 (DSK) variant offered in the same family.
Can the TPS3760E335DYYRQ1 be used with a 5 V supply rail?
Yes, the TPS3760E335DYYRQ1 supports supply voltages from 2.7 V to 65 V, fully covering 5 V operation. Its VDD pin functions independently of the SENSE pin, allowing VDD to be powered from a local 5 V regulator while SENSE monitors a separate 3.3 V rail - a configuration validated in the Typical Application Circuit.
Is the TPS3760E335DYYRQ1 latch-capable?
No, the TPS3760E335DYYRQ1 is not latch-capable. Table 4-1 confirms "No Latch" for this variant. Its RESET output deasserts automatically after the CTR-configured delay once the SENSE voltage returns within the hysteresis band. Latch functionality is only available in designated variants such as TPS3760H279DYYRQ1.
