Product details
Overview
TLE4699EXUMA1 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 (active-low RO down to VQ = 1 V), early warning comparator on SI pin, enable control (EN), and reverse polarity protection. It operates across −40 °C to +150 °C junction temperature with input range −42 V to +45 V, and is qualified per AEC-Q100 for engine control units and body electronics.
For engineers reviewing the TLE4699EXUMA1 datasheet, TLE4699EXUMA1 pinout, TLE4699EXUMA1 application, or TLE4699EXUMA1 equivalent, key selection criteria include its programmable reset threshold via RADJ, ultra-low off-state current (<1 µA), thermal shutdown, short-circuit protection, and PG-SSOP-14 EP package with exposed pad for enhanced thermal performance in space-constrained automotive modules.
Technical Context
The TLE4699EXUMA1 integrates a bandgap reference, precision error amplifier, and protection logic into a single die. Its reset generator uses internal hysteresis and external capacitor-based delay (via D pin) to provide reliable power-on reset timing independent of supply ramp rate.
The early warning function monitors the SI pin voltage against a user-adjustable threshold (via RADJ divider), triggering SO open-collector output before output collapse - enabling predictive system response. The regulator's LDO architecture achieves <300 mV dropout at 200 mA while maintaining line transient robustness under load steps.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Output Voltage | 5 V ±2% - stable MCU core/logic supply tolerant of battery variation and ripple. |
| Max Output Current | 200 mA - sufficient for microcontrollers, CAN transceivers, and sensor interfaces in ECUs. |
| Dropout Voltage | ≤300 mV @ 200 mA - enables operation down to VIN = 5.3 V, critical during cold-crank conditions. |
| Enable Input Threshold | VIL ≤ 0.8 V / VIH ≥ 2.0 V - compatible with standard 3.3 V/5 V logic without level shifters. |
| Reset Output | Active-low open-drain RO - supports wired-OR reset buses and pull-up to VQ or external rail. |
| Early Warning Output | Open-drain SO - signals impending undervoltage on monitored rail (SI) prior to regulator failure. |
| Operating Temp Range | −40 °C to +150 °C (TJ) - validated for under-hood placement in automotive power domains. |
Pinout & Package
Package: PG-SSOP-14 EP (exposed pad), thermally enhanced surface-mount package with 0.65 mm pitch and GND-connected exposed pad for PCB heat sinking.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| RADJ (Pin 1) | Reset threshold adjust | Connects to external resistor divider to set custom reset trigger voltage; tied to GND for default 4.65 V threshold. |
| D (Pin 3) | Reset delay capacitor | Accepts ceramic capacitor to GND to program reset timeout (e.g., 100 nF ≈ 100 ms delay). |
| GND (Pins 4, 6, 9, 10, 12) | Ground reference & thermal path | Multiple pins routed to internal GND plane and exposed pad - must be connected to large copper pour for thermal dissipation. |
| EN (Pin 5) | Regulator enable control | High-active digital input; draws <1 µA in disable state, enabling ultra-low-power sleep modes. |
| RO (Pin 7) | Reset output | Open-drain output active low; internal pull-up to VQ; sinks ≥5 mA at VOL ≤ 0.4 V. |
| SO (Pin 8) | Early warning output | Open-drain output active when SI voltage falls below programmed threshold; supports predictive fault handling. |
| Q (Pin 11) | 5 V regulated output | Stable 5 V supply; requires local 10 µF tantalum or 22 µF ceramic capacitor with ESR ≤ 1 Ω. |
| I (Pin 13) | Input supply | Main regulator input (−42 V to +45 V); requires local 100 nF ceramic capacitor to GND for noise suppression. |
| SI (Pin 14) | Sense input | Monitors external rail (e.g., battery or secondary supply); enables early warning before Q collapses. |
Key Features
| Feature | Design Value |
|---|---|
| Integrated Reset Generator | Programmable threshold (via RADJ) and delay (via D capacitor) eliminate need for external reset ICs in ECU designs. |
| Early Warning Comparator | Dedicated SI input with SO output enables pre-failure detection of brownout on auxiliary rails, improving system diagnostics. |
| Reverse Polarity Protection | Withstands −42 V input without damage - eliminates need for external series diode in battery-connected applications. |
| Ultra-Low Quiescent Current | <1 µA in disabled state - extends battery life in always-on vehicle modules (e.g., telematics, alarm systems). |
| Thermal Shutdown & Short-Circuit Protection | Auto-recovery after fault clearance - ensures robustness during load faults or ambient overtemperature events. |
Applications
| Engine Control Unit (ECU) Power Supply | Body Control Module (BCM) Core Regulation |
|---|---|

IC Role / Device Role / Timing Role: Protected voltage source with reverse polarity and short-circuit tolerance for safety-critical subsystems. Use Value: Survives jump-start reversal (−42 V) and motor back-EMF spikes; RO output synchronizes sensor data capture with system reset. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar automotive LDO regulator applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TLV70750PDBVR | Fixed 5 V output, 300 mA, but only rated to +125 °C and lacks reset/early warning functions. | No integrated reset or sense comparator - requires external components for system supervision. | Select when cost and footprint are prioritized over automotive qualification and functional integration. |
| TLE4275G | 5 V LDO with reset, but no early warning function and higher 600 mV dropout at 200 mA. | Lacks SI monitoring capability; less suitable for predictive diagnostics in next-gen ADAS modules. | Choose for legacy ECU upgrades where board space allows larger dropout margin and SO functionality is unused. |
Compared with TLV70750PDBVR and TLE4275G, the TLE4699EXUMA1 uniquely combines AEC-Q100 qualification, early warning output, and sub-300 mV dropout in a thermally optimized SSOP-14 EP package - making it optimal for new automotive designs requiring functional safety-aware power supervision.

FAQ
What is the minimum input voltage required for regulation at full 200 mA load?
The TLE4699EXUMA1 maintains 5 V regulation down to an input voltage of 5.3 V at 200 mA due to its 300 mV maximum dropout specification. Below this, output voltage drops linearly with input; operation below 4.5 V input is not guaranteed per datasheet functional range.
Can the reset threshold be adjusted below 4.65 V?
Yes - the RADJ pin accepts an external resistor divider between SI and GND to set thresholds as low as 3.0 V. The internal threshold is fixed at 4.65 V; lowering it requires connecting RADJ to the divider midpoint, with design verified using the formula in Section 8.2 of the datasheet.
Is the exposed pad on the PG-SSOP-14 EP package electrically connected?
Yes - the exposed pad is internally connected to GND and must be soldered to a PCB thermal pad tied to the system ground plane. Thermal performance degrades significantly if left floating or unconnected, increasing junction temperature by up to 35 °C at full load.
Does the early warning function require external components to operate?
No - SO activates when SI falls below the programmed threshold (default 4.65 V), requiring only connection of the monitored rail to SI. An external pull-up resistor on SO is optional but recommended for noise immunity in high-EMI environments like EPS or starter circuits.
