Product details
Overview
TLE63892GVXUMA2 from Infineon is a step-down DC/DC controller IC designed to drive an external P-channel MOSFET in automotive power supply systems. It supports input voltages up to 60V, delivers fixed 5V output at up to 2.3A, achieves ±3% output voltage accuracy, operates at 360kHz fixed switching frequency, and features integrated undervoltage reset and low-battery detection for engine control units and body electronics.
For engineers reviewing the TLE63892GVXUMA2 datasheet, TLE63892GVXUMA2 pinout, TLE63892GVXUMA2 application, or TLE63892GVXUMA2 equivalent, key selection criteria include its 100% duty-cycle capability for ultra-low dropout, <2µA shutdown current, SI_GND-controlled battery sense interface, and AEC-Q100 qualification for under-hood environments.
Technical Context
The TLE63892GVXUMA2 implements a current-mode PWM/PFM hybrid control scheme that enables seamless transition between modes without minimum load requirements. Its internal oscillator is synchronizable via the SYNC pin, and the 100% duty-cycle operation eliminates dropout at low VIN–VOUT differentials - critical for cold-crank automotive conditions.
It integrates two independent comparators: one for battery voltage sensing (SI/SI_GND/SO) with 1.25V internal reference, and another for output undervoltage reset (FB/RO) with 4.5–4.8V threshold and 50mV hysteresis. Both outputs are open-drain with internal 20kΩ pull-ups to VOUT.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Input Voltage Range | 2.1V to 60V - supports wide automotive battery range including cold-crank (4.5V) and load-dump (60V) transients. |
| Output Voltage | Fixed 5.0V ±3% - internally trimmed; no external feedback required for 5V version. |
| Max Output Current | 2.3A - determined by external P-MOSFET and sense resistor; peak-current-limited via CS pin. |
| Switching Frequency | 360kHz fixed - enables use of compact 47µH SMD inductors and reduces EMI compared to lower-frequency controllers. |
| Quiescent Current | <120µA at light load - achieved via PFM mode; extends battery life in always-on vehicle modules. |
| Shutdown Current | <2µA - enabled via SI_ENABLE pin; essential for low-power sleep states in body control modules. |
| Operating Temperature | −40°C to +150°C - qualified per AEC-Q100 Grade 0; suitable for under-hood placement near engine ECUs. |
Pinout & Package
Package: PG-DSO-14 (RoHS-compliant, thermally enhanced SOIC-14 with exposed pad).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 SI_ENABLE | Active-high enable for SI_GND | Controls low-impedance connection of SI_GND to GND; disables SO when low. |
| 2 FB | Feedback reference input | Internally connected to 5V divider; no external connection needed for fixed-output operation. |
| 3 VOUT | Buck output voltage monitor | Supplies internal bias circuitry; must connect directly to output capacitor node. |
| 4 GND | Analog ground reference | Primary signal return; separate from power ground paths to minimize noise coupling. |
| 5 SYNC | External clock synchronization input | Accepts TTL/CMOS clock up to 360kHz; overrides internal oscillator for EMI reduction. |
| 6 SI_GND | Sense comparator ground | Switched to GND or high-Z based on SI_ENABLE; sets reference point for battery-sense divider. |
| 7 SI | Battery sense comparator input | Compares against 1.25V internal reference; used for low-voltage warning or system wake-up. |
| 8 COMP | Loop compensation node | Connects RC network to GND for stability tuning of current-mode control loop. |
| 9 SO | Sense comparator output | Open-drain output with 20kΩ internal pull-up to VOUT; signals battery low condition. |
| 10 RO | Undervoltage reset output | Open-drain output with 20kΩ internal pull-up to VOUT; asserts reset below 4.5V output. |
| 11 BDS | Buck driver supply | Provides clamped gate-source voltage for P-MOSFET; requires 220nF ceramic capacitor to VS. |
| 12 GDRV | Gate drive output | Drives P-MOSFET gate between VS and BDS levels; supports fast turn-on/turn-off transitions. |
| 13 VS | Main device supply | Input rail connection; requires local 220nF ceramic + bulk low-ESR tantalum capacitance. |
| 14 CS | Current sense input | Monitors voltage drop across external sense resistor (e.g., 47mΩ); triggers MOSFET turn-off at peak current. |
Key Features
| Feature | Design Value |
|---|---|
| 100% duty-cycle operation | Enables regulation down to VIN − VOUT ≈ 0V; maintains 5V output during automotive cold-crank (≤4.5V battery). |
| Integrated undervoltage reset (RO) | 4.5–4.8V threshold with 50mV hysteresis ensures reliable microcontroller reset during brown-out events. |
| Dual comparator architecture | Separate SI/SO (battery sense) and FB/RO (output monitoring) paths allow independent system health checks. |
| Low-quiescent-current PFM/PWM mode | Reduces standby current to <120µA while maintaining regulation - critical for always-on telematics modules. |
| AEC-Q100 Grade 0 qualification | Validated for −40°C to +150°C junction temperature; meets automotive reliability and stress-test requirements. |
Applications
| Engine Control Unit (ECU) Power Supply | Body Control Module (BCM) Regulator |

Equivalent & Alternatives
The following parts are listed as comparable options for similar step-down controller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| LM5164QPWPRQ1 | Wide-input (3–65V) synchronous buck controller with integrated high-side FET; no external P-MOSFET required. | Reduces BOM count but lacks integrated battery sense comparator and dedicated SI_GND interface. | Select when board space is constrained and external MOSFET drive complexity must be eliminated. |
| TPS54240DGQR | 3.5–40V adjustable-output buck controller with 2.5A current limit; includes soft-start and thermal shutdown. | Does not support >40V input or AEC-Q100 Grade 0; no built-in undervoltage reset or battery sense comparator. | Select for non-automotive industrial applications where cost and feature set outweigh automotive qualification needs. |
Compared with LM5164QPWPRQ1 and TPS54240DGQR, the TLE63892GVXUMA2 uniquely combines AEC-Q100 Grade 0 operation, dual comparator functionality (SO/RO), and 100% duty-cycle capability - making it irreplaceable for safety-critical automotive power rails requiring cold-crank resilience and integrated system monitoring.

FAQ
What is the function of the SI_ENABLE pin on TLE63892GVXUMA2?
The SI_ENABLE pin is an active-high control input that switches the SI_GND terminal between low-impedance connection to GND and high-impedance state. When SI_ENABLE is high, SI_GND is tied to GND, enabling the SI comparator to monitor battery voltage using an external resistor divider. When low, SI_GND floats and SO becomes undefined - allowing selective activation of battery-sense functionality without additional external logic.
Can TLE63892GVXUMA2 operate with input voltage below 5V?
Yes - the device supports input voltages as low as 2.1V and features 100% duty-cycle operation, enabling continuous regulation even when VIN approaches VOUT. This capability is essential during automotive cold-crank events where battery voltage can fall to 4.5V while maintaining a stable 5V output for critical microcontrollers and sensors.
How does the RO (Reset Output) pin behave during undervoltage conditions?
The RO pin is an open-drain output with an internal 20kΩ pull-up to VOUT. It remains high under normal operation. When the regulated 5V output falls below the 4.5–4.8V threshold (with ~50mV hysteresis), RO pulls low to assert a hardware reset signal to connected MCUs or ASICs - providing deterministic brown-out protection without external components.
Is external feedback required for the 5V output version?
No - the TLE63892GVXUMA2 has the feedback divider internally connected to the 5V reference, so the FB pin is not externally routed. Unlike adjustable versions, this eliminates resistor tolerance errors and PCB layout sensitivity, improving output accuracy to ±3% across temperature and line/load conditions.
