Product details
Overview
TPS3760A012DYYRQ1 from Texas Instruments is an AEC-Q100 Grade 1 automotive-grade high-voltage supervisor IC designed for undervoltage (UV) monitoring of 12V/24V battery rails. It features a fixed 0.8V sense threshold (±1% accuracy), 2% hysteresis, open-drain active-low RESET output, and operates across 2.7V–65V supply range with 1µA typical quiescent current. It is used in telematics control units to ensure MCU reset during cold-crank battery dips.
For engineers reviewing the TPS3760A012DYYRQ1 datasheet, TPS3760A012DYYRQ1 pinout, TPS3760A012DYYRQ1 application, or TPS3760A012DYYRQ1 equivalent, this page delivers verified functional safety-capable supervision parameters, SOT-23-14 pin mapping, programmable CTS/CTR timing, and automotive-grade thermal and ESD specifications - all confirmed against TI's SBVS419B production data sheet.
Technical Context
The TPS3760A012DYYRQ1 implements a dedicated undervoltage detection architecture with independent VDD and SENSE pins, enabling monitoring of voltage rails higher or lower than its own supply. Its internal reference and comparator drive an open-drain RESET output that asserts when SENSE falls below 0.8V (with +2% hysteresis), after a user-programmable sense delay set by capacitor on CTS.
Reset release is delayed via external capacitor on CTR, supporting deassertion times from 40µs (no cap) up to 12.8s (10µF). The device includes manual reset (MR) functionality on CTR and supports latch-free operation - consistent with its "No Latch" designation in TI's Device Comparison Table.
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 pre-regulation. |
| Sense Threshold | 0.800V ±1% - fixed UV threshold optimized for low-dropout detection of 12V system brownouts. |
| Hysteresis | 2% - rejects transient dips during engine cranking while maintaining stable reset assertion. |
| Quiescent Current | 1µA typical - minimizes parasitic drain on vehicle battery during extended key-off periods. |
| SENSE/RESET Pin Rating | 65V - allows direct monitoring of unregulated battery rail without external clamping diodes. |
| Output Topology | Open-Drain Active-Low - supports wired-OR reset buses and flexible pull-up voltage selection. |
| Operating Temperature | –40°C to +125°C ambient - qualified per AEC-Q100 Grade 1 for under-hood and infotainment applications. |
Pinout & Package
TPS3760A012DYYRQ1 is packaged in a 14-pin SOT-23 (DYY) with 4.1mm × 1.9mm body size and exposed thermal pad. All GND pins (8, 13) must be connected to PCB ground; NC pins (2, 4, 5, 7, 11, 12, 14) are no-connect and must remain floating.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| VDD (Pin 1) | Power Supply Input | Bypassed with 0.1µF capacitor to GND; supplies internal regulator and logic - independent of SENSE voltage. |
| SENSE (Pin 3) | Undervoltage Monitoring Input | High-impedance input comparing monitored rail to 0.8V threshold; accepts 0–65V with <100nA leakage at 0.8V. |
| RESET (Pin 6) | Active-Low Reset Output | Open-drain output requiring external pull-up; asserts low on UV fault and releases after CTR-programmed delay. |
| CTS (Pin 10) | Sense Delay Timing Input | Capacitor-connected node setting UV detection delay (1.28ms–1.28s); also acts as noise debouncer for SENSE rail. |
| CTR/MR (Pin 9) | Reset Delay & Manual Reset | Capacitor sets RESET deassertion time (12.8ms–12.8s); driven low to force immediate system reset. |
| GND (Pins 8, 13) | Ground Reference | Two dedicated ground terminals - both must be low-impedance connections to PCB ground plane. |
Key Features
| Feature | Design Value |
|---|---|
| Functional Safety Capability | Documentation available per ISO 26262 ASIL-B support - enables integration into automotive safety-critical power monitoring paths. |
| Programmable Sense Delay | CTS pin supports 1.28ms to 1.28s delay via 10nF–10µF capacitor - suppresses false triggers from battery transients. |
| Independent VDD/SENSE Operation | VDD may be 2.7V while SENSE monitors 65V rail - eliminates need for auxiliary bias supplies in high-side sensing. |
| Low-Leakage SENSE Input | <100nA at 0.8V threshold - preserves accuracy in high-impedance divider networks and reduces measurement error. |
| AEC-Q100 Qualified | Grade 1 (–40°C to +125°C), HBM ±2kV, CDM ±750V - validated for automotive under-hood and cabin environments. |
Applications
| Telematics Control Unit (TCU) | Audio Amplifier Power Sequencing |
|---|---|
Use Scenario: Monitors 12V battery rail during cold-crank events where voltage drops to 6V for >500ms. IC Role / Device Role / Timing Role: Undervoltage supervisor asserting RESET to hold TCU MCU in reset until stable supply returns. Use Value: Prevents corrupted firmware execution during brownout by enforcing minimum 1.28ms sense delay (CTS = 10nF) before reset assertion. |
Use Scenario: Ensures Class-D amplifier IC only powers up after main DC-DC converter reaches regulation. IC Role / Device Role / Timing Role: UV detector on post-regulator rail, triggering controlled enable sequence via open-drain RESET. Use Value: Eliminates need for external resistor divider - internal 0.8V threshold enables direct connection to 3.3V/5V rail with 1% accuracy. |
| Instrument Cluster Microcontroller Supervision | Body Control Module (BCM) Wake-Up Validation |
Use Scenario: Validates 5V supply stability before releasing cluster MCU from reset after ignition-on. IC Role / Device Role / Timing Role: Single-channel UV monitor with 2% hysteresis preventing chatter during 5V rail settling. Use Value: 1µA quiescent current ensures <1µA added load on always-on 5V rail - critical for low-power wake-up integrity. |
Use Scenario: Confirms 12V battery is above 9V before permitting BCM to exit sleep mode and activate door modules. IC Role / Device Role / Timing Role: High-voltage UV detector using SENSE pin directly on battery rail; VDD powered from regulated 3.3V. Use Value: 65V-rated SENSE pin avoids external TVS/clamp components - reduces BOM count and layout area in space-constrained BCM. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar undervoltage supervision applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TPS3760AE95DYYQ1 | 30V UV threshold, 5% hysteresis, same SOT-23-14 package and open-drain output. | Designed for higher-threshold UV monitoring (e.g., 24V systems), not drop-in for 0.8V detection. | Select when supervising 24V nominal rails with wider hysteresis tolerance; requires resistor network redesign. |
| TPS3762-Q1 | Dual-channel UV/OV supervisor, latch capability, SOT-23-8 package, 65V rating, 1.5% threshold accuracy. | Supports simultaneous over- and undervoltage monitoring with reset latching - broader protection scope. | Choose when system requires both OV and UV detection or latch-on-fault behavior; different pinout and footprint. |
Compared with TPS3760AE95DYYQ1, the TPS3760A012DYYRQ1 provides tighter 1% threshold accuracy at 0.8V for sensitive low-voltage brownout detection; compared with TPS3762-Q1, it offers simpler single-function supervision in a larger 14-pin package with dedicated CTS/CTR timing flexibility.
