S6BP401AM2SN1B200

Overview

The S6BP401AM2SN1B200 is a specialized automotive power management integrated circuit (PMIC) from Infineon Technologies, belonging to the S6BP401 series. It integrates six output channels configured as four synchronous buck converters and two low-dropout linear regulators (LDOs). The device operates within an input voltage range of 2.97V to 5.5V and supports a junction temperature range of -40°C to 125°C. Key electrical specifications include a switching frequency of 2.1MHz for the buck converters. Output capabilities vary by channel, with specific ratings such as 1.2V at 2A and 1V at 3A available on designated outputs. The component is housed in a 40-pin QFN package measuring 6x6mm and is qualified to AEC-Q100 standards for automotive reliability.

Feature Summary

• Integrates multiple power conversion topologies including synchronous buck and LDO regulators within a single compact package.
• Designed specifically for automotive applications with AEC-Q100 qualification ensuring high reliability under harsh environmental conditions.
• Supports advanced driver-assistance systems (ADAS) through efficient multi-channel power distribution.

Applications

• Advanced Driver-Assistance Systems (ADAS)
• Automotive domain controllers
• Multi-rail power distribution in vehicle electronics

Procurement Notes

Verify the exact suffix 'M2' against official Infineon documentation to confirm pinout and functional compatibility, as suffixes often denote specific packaging or tape-and-reel configurations. Confirm current production status directly with the manufacturer, as automotive PMICs may undergo lifecycle changes. Ensure the selected variant matches the required thermal performance and output current specifications for the target ADAS application design.

Selection Notes

Select this component when designing automotive systems requiring a consolidated solution for multiple voltage rails. The integration of four buck and two LDO outputs reduces board space compared to discrete solutions. Consider the 2.1MHz switching frequency for EMI management and the wide operating temperature range suitable for under-hood or chassis-mounted locations. Verify that the 40-QFN package fits the mechanical constraints of the target PCB layout.
