Product details
Overview
S6BP501A00SN2B000 from Infineon Technologies (formerly Cypress) is a 3-channel automotive-grade PMIC integrating a high-voltage buck controller (DD3V), a synchronous buck converter with integrated FETs (DD1V), and a synchronous boost converter with integrated FETs (DD5V). It delivers 1.4 A at 1.0–1.3 V (DD1V), 1.6 A at 3.2–3.4 V (DD3V via SW3V), and 1.3 A at 5.0–5.2 V (DD5V), operating from 2.5 V to 42 V input - enabling stable power delivery during automotive cold cranking down to 2.5 V. It targets instrument cluster power systems requiring multi-rail, low-quiescent-current, and AEC-Q100 Grade-2 compliance.
For engineers reviewing the S6BP501A00SN2B000 datasheet, S6BP501A00SN2B000 pinout, S6BP501A00SN2B000 application, or S6BP501A00SN2B000 equivalent, key selection criteria include its triple-output architecture, 15 µA no-load quiescent current, SYNC/SSCG for EMI reduction, thermal warning (HOT) output, and independent PG monitors per rail - all in a wettable QFN-32 (5 mm × 5 mm) package.
Technical Context
This IC implements three independent switching regulators with distinct architectures: DD3V uses a current-mode buck controller driving external high- and low-side MOSFETs (DRVH3V/DRVL3V), while DD1V and DD5V integrate synchronous rectification FETs and operate up to 2.4 MHz. The DD3V channel supports 100% duty cycle and features one-fifth-divided clock operation (420 kHz typ internal).
Control logic includes automatic PWM/PFM mode switching (selectable via SYNC pin), spread-spectrum clock generation (SSCG) active under both internal and external clock modes, and comprehensive protection: UVLO (2.3 V typ), OVP, OCP, TSD, TWI, and per-rail UVD/OVD detection with open-drain PG outputs (PG1V/PG3V/PG5V).
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Input Voltage Range | 2.5 V to 42 V - supports full automotive battery range including cold-crank (2.5 V min) without dropout. |
| DD1V Output | 1.0 V to 1.3 V, 1.4 A max - adjustable via FB1V resistor divider; optimized for core logic rails. |
| DD3V Output | 3.2 V to 3.4 V, 1.6 A max via SW3V load switch - regulated by external FETs; supports 100% duty cycle. |
| DD5V Output | 5.0 V to 5.2 V, 1.3 A max - adjustable via FB5V; 2.1 MHz typical switching frequency enables compact 1.0 µH inductors. |
| Quiescent Current | 15 µA typ at no load - minimizes standby power loss in always-on automotive modules. |
| Shutdown Current | 1 µA typ - ensures ultra-low leakage during system sleep or ignition-off states. |
| AEC-Q100 Grade | Grade-2 (−40 °C to +105 °C ambient) - qualified for instrument cluster and body control module environments. |
Pinout & Package
Supplied in a wettable QFN-32 (VNG032) package measuring 5 mm × 5 mm with exposed thermal pad (EP), optimized for automotive thermal reliability and automated optical inspection (AOI) solder joint verification.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| FB1V (Pin 1) | Feedback input | Resistor-divider node setting DD1V output voltage; high-impedance input for precision regulation. |
| LX1V (Pin 3) | Power switch node | Connects to inductor and low-side FET source for DD1V buck stage; requires tight layout for EMI control. |
| PG1V (Pin 30) | Power good indicator | Open-drain output asserting low when DD1V is within ±5% of target; enables sequenced system enable. |
| SYNC (Pin 25) | Mode control / clock input | Configures PWM/PFM/auto mode for DD3V/DD5V; accepts external 360–480 kHz or 1.8–2.4 MHz clock for synchronization. |
| HOT (Pin 28) | Thermal warning flag | Open-drain output pulled low when junction temperature exceeds 145 °C (typ); signals thermal derating before shutdown. |
Key Features
| Feature | Design Value |
|---|---|
| Triple-output architecture | Dedicated buck controller (DD3V), integrated-buck (DD1V), and integrated-boost (DD5V) eliminate need for discrete regulators in cluster designs. |
| SSCG + SYNC synchronization | Reduces peak EMI amplitude by spreading spectrum across ±1% bandwidth; external clock sync enables board-level noise coordination. |
| Per-rail power good monitoring | Independent open-drain PG1V/PG3V/PG5V outputs allow fault-isolated power sequencing and diagnostics in ASIL-B systems. |
| Thermal warning with hot flag | HOT pin asserts before TSD activation, enabling firmware-controlled throttling or display dimming to maintain functionality. |
| Load-independent soft-start | Ensures monotonic VOUT ramp regardless of output capacitance or load, preventing inrush-induced supply droop on shared rails. |
Applications
| Instrument Cluster Power Supply | Automotive HUD Controller |
|---|---|
|
Use Scenario: Powering microcontroller, TFT LCD bias, CAN transceiver, and backlight LED driver in digital instrument clusters. IC Role / Device Role / Timing Role: Primary multi-rail PMIC delivering 1.2 V core, 3.3 V I/O, and 5.0 V interface rails with synchronized switching to suppress display flicker. Use Value: Eliminates 3+ discrete DC/DCs; SSCG reduces conducted EMI into sensitive analog sensor signal paths near the cluster. |

Use Value: HOT pin enables real-time thermal derating of laser current before lens focus shift occurs, maintaining projection accuracy. |
| Body Control Module (BCM) Subsystem | Automotive Gateway Node |
|
Use Scenario: Powering LIN transceivers, EEPROM, and wake-up logic in door module or seat control units. IC Role / Device Role / Timing Role: Provides always-on 3.3 V rail (DD3V) and switched 1.2 V/5.0 V rails (DD1V/DD5V) with 1 µA shutdown current for low-power wake capability. Use Value: Meets ISO 16750-2 quiescent current requirements for parked vehicle battery drain (<20 µA total system). |

IC Role / Device Role / Timing Role: Generates isolated 1.2 V core, 3.3 V PHY, and 5.0 V level-shifter rails; PG outputs feed watchdog and security monitor circuits. Use Value: Independent PG flags enable hardware-enforced boot sequence validation - critical for UNECE R155 compliance. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar multi-output automotive PMIC applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MPQ4333-AEC1 (Monolithic Power) | Single 3A buck (not triple-output); no boost or load switch; lacks SSCG and HOT pin. | Requires additional ICs for 3.3 V/5.0 V rails; no thermal warning or per-rail PG. | Select only if design needs only one high-current rail and can add discrete regulators. |
| TPS65381A-Q1 (TI) | Three buck outputs only (no boost); integrates CAN transceiver; higher IQ (35 µA) and larger QFN-48 package. | Built-in CAN PHY simplifies gateway integration but increases BOM cost for non-CAN use cases. | Prefer when CAN interface co-location is required; avoid if boost rail or minimal footprint is critical. |
Compared with MPQ4333-AEC1 and TPS65381A-Q1, S6BP501A00SN2B000 uniquely combines buck, boost, and load-switch outputs in one AEC-Q100 Grade-2 device with SSCG, HOT flag, and 15 µA quiescent current - making it optimal for space-constrained instrument clusters needing full rail independence and thermal-aware operation.

FAQ
What is the function of the HOT pin (Pin 28)?
The HOT pin is an open-drain thermal warning indicator that pulls low when the IC's junction temperature reaches approximately 145 °C. It activates before thermal shutdown (TSD) to allow system firmware to reduce load or adjust display brightness, preserving functionality during transient overheating. It must be pulled up externally with a 10 kΩ resistor to VB or VOUT3V.
Can DD3V operate with 100% duty cycle, and what is its minimum input voltage?
Yes, DD3V supports 100% duty cycle operation, enabling regulation down to VIN = VOUT (3.2–3.4 V). Its input voltage range is 2.5 V to 42 V, allowing stable output even during automotive cold cranking events where battery voltage drops to 2.5 V - provided the external FETs and inductor are rated for the resulting peak currents.
How does the SYNC pin configure PWM/PFM mode for DD5V and DD3V?
When SYNC is pulled low, DD5V and DD3V enter PFM mode for highest light-load efficiency. When SYNC is pulled high, they operate in fixed-frequency PWM mode. Floating or undefined levels are not allowed; tie to GND or VB via resistor. This pin does not affect DD1V, which uses automatic PWM/PFM switching by default.
Is external compensation required for the DD1V and DD5V converters?
No - DD1V and DD5V include built-in phase compensators optimized for standard 1.0 µH inductors and 22 µF ceramic output capacitors. External compensation is only needed for DD3V, which uses an external buck controller architecture requiring RC network on COMP pin (not present on this device - compensation is implemented internally via DRVH3V/DRVL3V loop design).
