Product details
Overview
TLE63893GV50XUMA1 from Infineon Technologies is a fixed 5V step-down DC/DC controller driving an external P-channel MOSFET, supporting input voltages up to 60V, delivering up to 2.3A output current, featuring 360kHz fixed switching frequency, integrated undervoltage reset with 1V hysteresis, and AEC-Q100 qualification for automotive power supply rails.
For engineers reviewing the TLE63893GV50XUMA1 datasheet, TLE63893GV50XUMA1 pinout, TLE63893GV50XUMA1 application, or TLE63893GV50XUMA1 equivalent, key selection criteria include its 5V fixed output accuracy (±3%), 120µA light-load quiescent current, RO/SO open-drain outputs with internal 20kΩ pull-up to VOUT, SI comparator for battery sensing, and PG-DSO-14-1 package compatibility with high-temperature automotive environments.
Technical Context
The TLE63893GV50XUMA1 implements a current-mode PWM/PFM hybrid control scheme enabling 100% duty cycle operation for ultra-low dropout, eliminating minimum load requirements while maintaining regulation down to 1mA. Its internal low-battery comparator (SI input referenced to 1.25V) and undervoltage reset circuit (RO threshold ~4.65V ±150mV with 1V hysteresis) operate independently of the main regulator loop.
It drives external P-MOSFETs via GDRV with clamped gate drive supplied by BDS–VS bootstrap capacitor, supports external clock synchronization via SYNC pin, and uses FB internally tied to a precision voltage divider for fixed 5V output-removing need for external feedback resistors.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Input Voltage Range | 2.1V to 60V - supports wide automotive battery transients including cold-crank and load-dump conditions |
| Output Voltage | Fixed 5.0V ±3% - factory-trimmed internal reference eliminates external resistor network |
| Max Output Current | 2.3A - determined by external P-MOSFET and inductor selection, not IC-limited |
| Switching Frequency | 360kHz fixed - enables use of compact 47µH SMD inductors and reduces EMI filtering burden |
| Quiescent Current | 120µA at light load - extends battery runtime in always-on vehicle modules |
| Reset Threshold | 4.65V ±150mV with 1V hysteresis - ensures clean system restart after brown-out recovery |
| Operating Temperature | −40°C to +150°C junction - qualified per AEC-Q100 Grade 0 for under-hood applications |
Pinout & Package

| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 SI_ENABLE | Active-high enable for SI_GND switch | Controls connection of SI_GND to GND; SO/RO undefined when low |
| 2 FB | Feedback reference input | Internally connected to 5V divider; no external components required |
| 3 VOUT | Buck output voltage sense | Supplies internal bias circuitry; must connect directly to output capacitor |
| 4 GND | Analog ground reference | Primary signal return for FB, COMP, CS, and internal regulators |
| 5 SYNC | External clock input | Overrides internal 360kHz oscillator; accepts TTL/CMOS logic-level signals |
| 6 SI_GND | Low-battery comparator ground | Switched to GND or high-Z based on SI_ENABLE state |
| 7 SI | Sense comparator input | Compares external voltage to internal 1.25V reference; used for battery monitoring |
| 8 COMP | Loop compensation node | Connects RC network to GND for stability tuning of current-mode control |
| 9 SO | Sense comparator output | Open-drain output pulled up to VOUT via 20kΩ; asserts low when SI < 1.25V |
| 10 RO | Reset output | Open-drain output pulled up to VOUT via 20kΩ; asserts low when VOUT < 4.65V |
| 11 BDS | Bootstrap driver supply | Provides clamped gate-source voltage for P-MOSFET drive; requires ceramic cap to VS |
| 12 GDRV | Gate drive output | Swings between VS and BDS levels; drives P-MOSFET gate with fast edge rates |
| 13 VS | Main supply input | Accepts 2.1–60V; requires local 220nF ceramic + bulk low-ESR tantalum capacitance |
| 14 CS | Current sense input | Monitors voltage drop across external sense resistor to limit peak inductor current |
Key Features
| Feature | Design Value |
|---|---|
| 100% Duty Cycle Operation | Enables regulation down to VIN − VOUT ≈ 0.3V, critical for cold-crank (6.5V) start-up into 5V rail |

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 |
|---|---|---|---|
| TLV62569DRVR | 3.0–5.5V input only; integrated MOSFET; 2A max; no SI/RO/SO functions | Lacks battery sense, reset, and high-voltage capability - unsuitable for automotive primary rail | Select only for low-voltage consumer applications where 60V tolerance and diagnostics are unnecessary |
| LM5164QDDARQ1 | Wide-input (3–65V); integrated high-side MOSFET; 300kHz–2.2MHz sync; no SI comparator or RO hysteresis | Requires external reset IC; lacks on-chip low-battery flag; higher BOM count for same functionality | Choose when higher efficiency at light loads or programmable frequency is prioritized over integrated diagnostics |
Compared with TLV62569DRVR and LM5164QDDARQ1, the TLE63893GV50XUMA1 uniquely integrates automotive-grade reset (1V hysteresis), battery sense (SI/SO), and 60V operation in a single PG-DSO-14 package-reducing component count and validation effort for AEC-Q100-compliant 5V rails.

FAQ
What is the function of the SI_ENABLE pin on TLE63893GV50XUMA1?
The SI_ENABLE pin controls the switching state of the SI_GND terminal: when high, SI_GND is connected to GND with low impedance; when low, SI_GND enters high-impedance mode and SO/RO outputs become undefined. This allows safe isolation of the battery-sense circuit during system standby without affecting main regulator operation.
Can TLE63893GV50XUMA1 be used with an N-channel MOSFET instead of a P-channel?
No. The TLE63893GV50XUMA1 is designed exclusively for external P-channel MOSFETs, as its GDRV output swings between VS and BDS to provide proper gate-source voltage control. Using an N-channel device would require level-shifting circuitry and is not supported by the internal driver architecture or datasheet application guidance.
How does the RO output behave during power-up and brown-out events?
The RO output remains high-impedance until VOUT reaches ~4.5V, then transitions to active-low when VOUT drops below 4.65V (typical). With 1V hysteresis, RO stays low until VOUT rises above ~5.65V, ensuring glitch-free reset assertion and release during battery transients and slow-rising supplies.
Is external compensation required for stable operation of TLE63893GV50XUMA1?
Yes. A Type II RC compensation network must be connected between COMP and GND to stabilize the current-mode control loop. Typical values are 10kΩ in series with 1nF capacitor, but exact values depend on selected inductor, output capacitor ESR, and desired phase margin-designers must verify loop response using the COMP pin's transimpedance characteristics.
