Product details
Overview
TLE4699GMXUMA1 from Infineon Technologies is an automotive-grade monolithic low-dropout linear voltage regulator delivering a fixed 5 V ±2% output at up to 200 mA, featuring integrated reset generation, early warning comparator, enable control, reverse polarity protection, short-circuit and overtemperature shutdown-designed for microprocessor supply in engine control units and body electronics.
For engineers reviewing the TLE4699GMXUMA1 datasheet, TLE4699GMXUMA1 pinout, TLE4699GMXUMA1 application, or TLE4699GMXUMA1 equivalent, key selection criteria include its −42 V to +45 V input range, <1 µA shutdown current, reset output active down to VQ = 1 V, programmable reset threshold/delay, and PG-DSO-14 thermal performance under AEC-Q100 qualification.
Technical Context
The TLE4699GMXUMA1 integrates a bandgap-referenced LDO core with independent supervisory blocks: a reset generator triggered by output voltage monitoring, an early warning comparator sensing external rail (SI), and digitally controlled enable logic-all operating across −40 °C to +150 °C junction temperature. Its architecture supports fail-safe microcontroller boot sequencing via open-collector RO/SO outputs with internal pull-ups to Q.
Input compensation is handled through dedicated I-pin filtering, while thermal robustness relies on the PG-DSO-14 package's exposed heat sink area connected via pins 3/4/5/10/11/12 to GND. The RADJ pin enables threshold adjustment via external resistor divider, and D-pin capacitor sets reset delay time independently of output load.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Output Voltage | 5 V ±2% - stable MCU core/sensor supply under battery transients and load steps |
| Max Output Current | 200 mA - sufficient for low-power ECUs, CAN transceivers, and sensor interfaces |
| Dropout Voltage | Typ. 300 mV @ 200 mA - enables operation down to 5.3 V input during cold-crank (≥6 V) |
| Input Voltage Range | −42 V to +45 V - withstands load dump, reverse battery, and jump-start conditions |
| Quiescent Current | <1 µA in disable mode - preserves battery during vehicle sleep states |
| Reset Threshold | Programmable 4.25–4.75 V via RADJ - configurable brown-out detection for system-specific margins |
| Operating Temp | −40 °C to +150 °C (Tj) - qualified for under-hood ECU placement per AEC-Q100 Grade 0 |
Pinout & Package
Package: PG-DSO-14 (RoHS-compliant, thermally enhanced SOIC with exposed pad footprint; pin-compatible with TLE4299).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 RADJ | Reset threshold adjust | Connect external resistor divider to set custom reset voltage; tie to GND for default 4.5 V |
| 2 D | Reset delay timing | Capacitor to GND sets reset assertion delay (e.g., 100 nF ≈ 100 ms); open if unused |
| 3,4,5,10,11,12 GND | Ground / thermal path | All must connect to PCB heatsink area for thermal management and noise immunity |
| 6 EN | Enable control | High-active digital input; tie to I-pin for always-on operation |
| 7 RO | Reset output | Open-collector, pulled up internally to Q; sinks current when output drops below threshold |
| 8 SO | Sense output | Open-collector early-warning signal; asserts before reset when SI falls below threshold |
| 9 Q | 5 V regulated output | Requires local ceramic capacitor (10 µF, ≤50 mΩ ESR) for stability and transient response |
| 13 I | Input supply & line compensation | Primary VIN connection; decoupling cap to GND suppresses high-frequency line noise |
| 14 SI | Sense input | Monitors external rail (e.g., main battery); connect to Q for self-supervision |
Key Features
| Feature | Design Value |
|---|---|
| Integrated reset generator | Active-low RO output with user-programmable threshold (4.25–4.75 V) and delay (capacitor-set) |
| Early warning comparator | SO pin asserts prior to reset, enabling graceful MCU shutdown or diagnostics before brown-out |
| Reverse polarity protection | Withstands −42 V input without damage-eliminates need for external series diode |
| Ultra-low shutdown current | <1 µA at VEN = 0 V ensures ≤1 µA system leakage during vehicle sleep modes |
| AEC-Q100 Grade 0 qualification | Validated for 150 °C junction operation-supports placement in high-temp engine compartments |
Applications
| Engine Control Unit (ECU) Power Supply | Body Control Module (BCM) Sensor Hub |
|---|---|
|

Equivalent & Alternatives
The following parts are listed as comparable options for similar automotive LDO regulator applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TLE4299G | Same PG-DSO-14 footprint, but lacks early warning comparator and has fixed 4.5 V reset threshold | No SO pin; less flexible brown-out response; suitable only where pre-reset alert is unnecessary | Select when cost sensitivity outweighs diagnostic capability and reset threshold flexibility |
| TLV73350PDBVR | 300 mA output, 250 mV dropout, but rated only to 125 °C and not AEC-Q100 qualified | Not approved for under-hood use; limited to cabin or infotainment modules | Choose only for non-safety, non-under-hood designs requiring higher current and lower dropout |
Compared with TLE4699GMXUMA1, TLE4299G offers pin compatibility without early warning or adjustable reset, while TLV73350PDBVR trades automotive qualification and thermal rating for higher current and lower dropout-making TLE4699GMXUMA1 uniquely suited for AEC-Q100 Grade 0 environments demanding full fault supervision.

FAQ
What is the minimum input voltage required for regulation at full 200 mA load?
The TLE4699GMXUMA1 maintains 5 V regulation down to an input voltage of 5.3 V at 200 mA load, based on its typical 300 mV dropout voltage. This ensures stable operation during automotive cold-crank events where battery voltage may dip to 6 V, with margin for trace resistance and transient droop.
How is the reset delay time configured, and what capacitor value yields ~200 ms?
Reset delay is set by a ceramic capacitor between Pin 2 (D) and GND. Per the datasheet's characteristic curve, a 220 nF capacitor produces approximately 200 ms delay at 25 °C. Tolerance and temperature drift affect accuracy; design margin is recommended for safety-critical timing.
Can the SO (Sense Output) pin be used independently of the RO (Reset Output) pin?
Yes. SO is driven by a separate comparator monitoring SI voltage against a threshold derived from RADJ, while RO responds to Q voltage. SO asserts earlier than RO, allowing independent use for predictive diagnostics or pre-fault logging without affecting reset behavior.
Is external reverse polarity protection required when using TLE4699GMXUMA1?
No. The device incorporates internal reverse polarity protection rated to −42 V, verified per AEC-Q100 stress testing. No external diode or MOSFET is needed, reducing BOM count and PCB area while maintaining protection integrity across temperature and lifetime.
