Product details
Overview
TLE63892GVXUMA1 from Infineon Technologies is a step-down DC/DC controller IC designed to drive an external P-channel MOSFET in automotive power supply systems. It operates from 5V to 60V input, delivers up to 2.3A output current, features fixed 5V output with ±3% accuracy, 360kHz switching frequency, and integrated undervoltage reset with 1V hysteresis - used in engine control units for stable 5V rail generation under wide battery voltage transients.
For engineers reviewing the TLE63892GVXUMA1 datasheet, TLE63892GVXUMA1 pinout, TLE63892GVXUMA1 application, or TLE63892GVXUMA1 equivalent, key selection criteria include its AEC-Q100 qualification, 2µA shutdown current, SI comparator with 1.25V internal reference, RO open-drain reset output, and compatibility with high-side PMOS buck topologies requiring minimal external components.
Technical Context
The TLE63892GVXUMA1 implements a current-mode PWM/PFM hybrid control scheme enabling 100% duty cycle operation for ultra-low dropout performance, eliminating minimum load requirements. Its internal oscillator runs at 360kHz but accepts external synchronization via the SYNC pin, supporting timing-critical multi-rail systems.
It integrates dual comparators: one for low-battery detection (SI input vs. 1.25V reference, SO output) and another for output undervoltage monitoring (RO output with 1V hysteresis). The device uses VS as main supply, BDS for gate-driver bootstrap, and GDRV to swing between VS and BDS to drive the PMOS gate.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Input Voltage Range | 5V to 60V - supports full automotive battery range including cold-crank (6.5V) and load-dump (60V) events. |
| Output Voltage | Fixed 5V ±3% - internally trimmed; no external feedback required for nominal 5V rail generation. |
| Max Output Current | 2.3A - defines maximum continuous load capability when paired with suitable external PMOS and inductor. |
| Switching Frequency | 360kHz fixed, sync-capable - enables use of compact SMD inductors (e.g., 47µH) and reduces EMI filtering burden. |
| Quiescent Current | <120µA at light load - extends battery life in always-on vehicle modules like body controllers. |
| Shutdown Current | ≤2µA - achieved via SI_ENABLE pin; critical for low-power sleep modes in telematics and gateway ECUs. |
| Operating Temperature | −40°C to +150°C - qualified per AEC-Q100 Grade 0, enabling placement near engine compartments. |
Pinout & Package
Package: PG-DSO-14-1 (14-pin exposed-pad SOIC), thermally enhanced for automotive power dissipation.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 SI_ENABLE | Active-high enable for SI_GND switch | Controls low-impedance connection of SI_GND to GND; SO/RO outputs undefined 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 sense | Supplies internal bias circuitry; must connect directly to output capacitor node. |
| 4 GND | Analog ground reference | Primary signal return for FB, COMP, CS, and internal comparators; separate from power ground paths. |
| 5 SYNC | External clock input | Overrides internal 360kHz oscillator; allows synchronized switching across multiple rails to reduce beat frequencies. |
| 6 SI_GND | Low-battery comparator ground | Switched to GND or high-Z by SI_ENABLE; forms reference leg for SI voltage divider. |
| 7 SI | Sense comparator input | Compares external voltage against 1.25V internal reference; used for battery monitoring or custom threshold detection. |
| 8 COMP | Control loop compensation node | Connects RC network to GND to stabilize current-mode control loop; sets phase margin and transient response. |
| 9 SO | Sense comparator output | Open-drain output pulled up to VOUT via 20kΩ; signals low-battery condition (e.g., <11.5V). |
| 10 RO | Undervoltage reset output | Open-drain output pulled up to VOUT via 20kΩ; asserts reset below 4.5–4.8V with 1V hysteresis. |
| 11 BDS | Bootstrap driver supply | Provides clamped gate-source voltage for PMOS driver; requires ceramic cap to VS. |
| 12 GDRV | Gate drive output | Swings between VS and BDS levels; directly drives gate of external high-side P-MOSFET. |
| 13 VS | Main supply input | Primary power input (5–60V); 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 peak-current limit shutdown. |
Key Features
| Feature | Design Value |
|---|---|
| 100% Duty Cycle Operation | Enables regulation down to VIN − VDROP ≈ VIN − 0.3V, critical for cold-crank support in 12V systems. |
| Integrated Undervoltage Reset (RO) | Provides system-level reset with 1V hysteresis, eliminating need for discrete supervisor IC in ECU designs. |
| On-Chip Low-Battery Detector (SI/SO) | Uses internal 1.25V reference to monitor battery health without external precision references or op-amps. |
| AEC-Q100 Qualified | Validated for automotive Grade 0 (−40°C to +150°C junction), ensuring reliability in under-hood applications. |
| Sync-Capable Oscillator | Allows deterministic timing alignment across multiple DC/DC rails, reducing conducted EMI peaks in multi-converter systems. |
Applications

Equivalent & Alternatives
The following parts are listed as comparable options for similar step-down DC/DC controller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| LM5164QDDARQ1 | Wide-input (4.5–65V), adjustable output, 1.5A max, 100% duty cycle, but requires external MOSFET drivers and lacks integrated RO/SO comparators. | No built-in reset or battery monitor; needs additional supervisor IC and comparator for same functionality. | Choose when adjustable output and higher VIN max are prioritized over integration and footprint savings. |
| MAX20004AATP/V+T | 5V fixed output, 2.5A, 2.2MHz switching, AEC-Q100, but only supports NMOS high-side with bootstrap; no SI/RO comparators. | Lacks battery sense and reset functions; requires external components for undervoltage protection. | Select for higher-frequency, smaller inductor designs where integration of monitoring is handled elsewhere. |
Compared with LM5164QDDARQ1 and MAX20004AATP/V+T, TLE63892GVXUMA1 offers superior functional integration for automotive 5V rails - combining reset, battery monitoring, and PMOS drive in one DSO-14 package - reducing BOM count and layout complexity without sacrificing AEC-Q100 compliance or thermal performance.

FAQ
What is the function of the SI_ENABLE pin on TLE63892GVXUMA1?
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 low, SI_GND floats and SO/RO outputs become undefined; when high, SI_GND connects to GND, enabling proper operation of the SI comparator and RO reset circuit. It does not control main device enable - that function is absent in the -GV50 variant.
Can TLE63892GVXUMA1 be used with an N-channel MOSFET instead of a P-channel?
No - TLE63892GVXUMA1 is designed exclusively for high-side P-channel MOSFET drive. Its GDRV output swings between VS and BDS to provide proper gate-source voltage for PMOS turn-on. Using an NMOS would require a floating high-side driver or charge pump, which this IC does not support. The datasheet explicitly specifies "external P-channel MOSFET" in all application circuits.
How does the RO output behave during undervoltage conditions?
The RO pin is an open-drain output pulled up to VOUT via an internal 20kΩ resistor. It remains high under normal operation and pulls low when VOUT falls below the undervoltage threshold (4.5–4.8V), with 1V hysteresis to prevent oscillation. This provides a clean, debounced reset signal to microcontrollers without requiring external pull-up resistors or RC filters.
Is external compensation required for stable operation?
Yes - the COMP pin requires an external RC compensation network connected to GND to stabilize the current-mode control loop. Typical values cited in the datasheet include a 1nF capacitor and 10kΩ resistor. Omitting or mis-sizing this network causes instability, overshoot, or oscillation in transient response, especially under varying load or input conditions.
