Product details
Overview
S6BP502A00SN2B000 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 operates from 2.5 V to 42 V input, delivers up to 2.0 A on DD1V, 1.9 A via SW3V load switch, and 1.3 A on DD5V, and supports AEC-Q100 Grade-2 for instrument cluster power rails.
For engineers reviewing the S6BP502A00SN2B000 datasheet, S6BP502A00SN2B000 pinout, S6BP502A00SN2B000 application, or S6BP502A00SN2B000 equivalent, key selection criteria include cold-crank operation down to 2.5 V, 2.1 MHz switching frequency for compact magnetics, spread-spectrum clocking for EMI reduction, independent power-good monitoring per rail, and thermal warning output.
Technical Context
This PMIC implements three independent DC/DC regulation paths: DD1V (1.0–1.3 V, 2.0 A max) uses current-mode synchronous buck with internal FETs; DD5V (5.0–5.2 V, 1.3 A) employs synchronous boost architecture; DD3V (3.2–3.4 V) is a high-side controller driving external FETs, supporting 100% duty cycle and operating at one-fifth the base clock frequency. All channels feature PFM/PWM auto-switching and soft-start.
The IC integrates protection logic including UVLO (2.3 V typ), OVP (115% nominal), OCP (cycle-by-cycle + hiccup), TSD (150 °C), and TWI (125 °C). Its SYNC pin enables external clock synchronization (1.8–2.4 MHz for DD1V/DD5V; 360–480 kHz for DD3V) and selects PWM-only, auto PWM/PFM, or PFM-only modes for DD3V/DD5V.
Key Specifications

Applications
| Instrument Cluster Power Supply | ADAS Camera Module Bias |
|---|---|
Use Scenario: Powering microcontroller, display driver, and CAN transceiver in digital instrument clusters under wide battery voltage range (6–16 V nominal, down to 2.5 V cold crank). 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 startup and independent fault reporting.

IC Role / Device Role / Timing Role: Automotive-qualified PMIC used in industrial setting for extended temperature (-40 °C to +105 °C) and long-lifecycle stability. Use Value: AEC-Q100 qualification ensures <10 FIT failure rate; SYNC pin allows synchronization to system clock to avoid beat frequencies with motor drives. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar multi-rail automotive PMIC applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MPQ4333-AEC1 | Single 3A buck (not 3-channel); no boost or load switch; lacks SSCG and thermal warning | Requires external LDOs or converters for 3.3 V/5.0 V rails; no built-in sequencing or rail-specific PG | Select when only one high-current rail is needed and cost-per-rail is prioritized over integration |
| S6BP401A | 6-channel PMIC with identical architecture; adds two extra bucks and one LDO; larger QFN-40 package | Targets ADAS domain controllers requiring more rails; higher BOM count and layout complexity | Select when scaling beyond instrument cluster to multi-ECU platforms needing unified power architecture |
Compared with MPQ4333-AEC1 and S6BP401A, S6BP502A00SN2B000 uniquely balances integration (3 rails + load switch + SSCG + HOT), compact 5×5 mm footprint, and automotive qualification-making it optimal for space-constrained instrument clusters where rail count, EMI, and thermal awareness are co-constrained.

FAQ
What is the function of the HOT pin?
The HOT pin is an open-drain thermal warning indicator that asserts low when the junction temperature reaches 125 °C. It is not a shutdown signal-thermal shutdown occurs at 150 °C. Designers use HOT to trigger firmware-based thermal derating (e.g., reducing display brightness or CPU frequency) before critical thermal events, improving system resilience without interrupting operation.
How does the SYNC pin configure PWM/PFM operation?
When SYNC is pulled low, DD3V and DD5V enter PFM-only mode for ultra-low quiescent current. When SYNC is high, they operate in automatic PWM/PFM mode. Floating or externally clocked SYNC enables fixed-frequency PWM. This configuration is confirmed in Table 8-2 of the datasheet and applies only to DD3V and DD5V-not DD1V, which remains PWM-only.
Can S6BP502A00SN2B000 replace S6BP501A in existing designs?
Yes-S6BP502A00SN2B000 is pin-compatible and functionally identical to S6BP501A except for maximum output current ratings: S6BP502A delivers 2.0 A on DD1V (vs. 1.4 A for S6BP501A) and 1.9 A via SW3V (vs. 1.6 A). No layout or firmware changes are required; the higher current capability provides margin for future performance upgrades or worst-case thermal derating.
What is the role of the IN3V pin?
IN3V supplies power to both the SW3V load switch and the PVCC1V rail for DD1V's internal FET drivers. It must be connected to a clean, low-impedance 5–12 V source-separate from VIN-to ensure stable gate drive during high-current DD1V switching and reliable SW3V turn-on. Using IN3V instead of VIN avoids noise coupling into sensitive analog blocks.
