Product details
Overview
S6BP502A00SN2B200 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 2.0 A at DD1V, 1.9 A via SW3V load switch, and 1.3 A at DD5V, with input voltage support down to 2.5 V for cold-cranking operation in instrument clusters.
For engineers reviewing the S6BP502A00SN2B200 datasheet, S6BP502A00SN2B200 pinout, S6BP502A00SN2B200 application, or S6BP502A00SN2B200 equivalent, key selection criteria include AEC-Q100 Grade-2 qualification, wettable QFN-32 package, independent power-good monitoring per channel, spread-spectrum clocking for EMI reduction, and 15 µA quiescent current under no-load conditions.
Technical Context
The IC implements three independent DC/DC topologies: DD3V uses external high-side/low-side MOSFETs in a current-mode buck controller architecture with 100% duty-cycle capability; DD1V and DD5V employ internal synchronous rectification FETs in fixed-frequency current-mode buck and boost converters respectively. All channels support automatic PWM/PFM mode switching controlled by the SYNC pin.
Each output features dedicated overvoltage (OVD), undervoltage (UVD), and power-good (PG) monitoring with open-drain outputs (PG1V, PG3V, PG5V), plus thermal warning (HOT) indication. The SSCG operates with both internal (420 kHz / 2.1 MHz) and externally synchronized clocks (360–480 kHz for DD3V; 1.8–2.4 MHz for DD1V/DD5V).

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 3 A buck converter (no boost or controller channel); lacks SSCG and thermal warning pin | Requires external boost IC for 5 V rail; no HOT pin for predictive thermal management | Select when only 1.2 V/3.3 V rails needed and EMI filtering is handled externally |
| TPS65381A-Q1 | Three-channel (2 buck + 1 LDO), no boost; 1.5 A DD1V max; no spread-spectrum or 100% duty-cycle capability | Cannot generate 5 V from low VIN; limited cold-crank support (min 3.0 V input) | Select when 5 V rail is supplied separately and thermal warning is not required |
Compared with MPQ4333-AEC1 and TPS65381A-Q1, S6BP502A00SN2B200 uniquely integrates boost + buck controller + buck in one AEC-Q100 package with SSCG, HOT pin, and 2.5 V cold-crank operation - enabling complete cluster power solution without supplemental ICs.

FAQ
What is the function of the HOT pin on S6BP502A00SN2B200?
The HOT pin is an open-drain thermal warning indicator that asserts low when the IC's junction temperature reaches 145 °C - 15 °C below the 160 °C thermal shutdown threshold. It enables the host system to initiate thermal throttling or logging before forced reset, improving system diagnostics and graceful degradation in high-ambient environments like dashboard-mounted clusters.
How does the SYNC pin configure PWM/PFM operation?
When SYNC is pulled low, DD3V and DD5V enter PFM mode for ultra-low quiescent current (15 µA); when SYNC is high, they operate in fixed-frequency PWM mode. An external clock applied to SYNC synchronizes all channels' switching frequencies, reducing beat frequencies and simplifying EMI filter design in multi-PMIC systems.
Can S6BP502A00SN2B200 support 5 V output directly from a 12 V battery?
Yes - the integrated DD5V boost converter generates 5.0–5.2 V from inputs as low as 2.5 V, making it suitable for direct 12 V battery connection. Its 1.3 A output drives LED backlights or USB peripherals without external boost stages, and its 2.1 MHz switching frequency allows use of 1.0 µH inductors for minimal board space.
What is the role of the SW3V load switch in the S6BP502A00SN2B200 architecture?
SW3V is a high-side load switch controlled by the DD3V buck controller block, delivering up to 1.9 A at 3.2–3.4 V from the IN3V input (e.g., 5 V rail). It provides fast turn-on/off control, current limiting, and thermal protection independent of the main DD3V regulator - ideal for powering 3.3 V I/O rails that require dynamic enable/disable sequencing.
