S6BP401A Six-channel Advanced Driver Assistance System PMIC

Cypress’s S6BP401A Automotive PMIC has been created for Advanced Driver Assistance Systems (ADAS). This single-chip power management solution has a 6-channel power output, which includes a 4-channel DC/DC converter and 2-channel LDO. Integrating output setting impedance and phase compensation circuits internally for all channels, the S6BP401A reduces the PCB size and bill of materials, enabling a smaller, cost-effective ADAS.

The S6BP401A PMIC is equipped with a built-in windowed watchdog timer, separate pins to turn on/off each channel, and dedicated pins to monitor the power integrity of each channel.

Key Features:

  • 6-ch Power Management IC: 4-ch Buck converters, 2-ch LDOs
  • Input voltage range: 4.5 V-5.5 V
  • Switching Frequency: 2.1 MHz
  • Synchronization with external clock from 1.8 MHz to 2.4 MHz
  • Maximum operating temperature: 125°C
