DESCRIPTION：
The SCT61250S is a highly integrated power management IC (PMIC) optimized for automotive camera system. It integrates three high-efficiency synchronous buck converters (HV Buck1, LV Buck2, LV Buck3), one high-PSRR low noise LDO (LDO4) and one general LDO (LDO5) with OV/UV monitoring and flexible power sequence for all outputs.
Buck1 has an input voltage range from 4V to 19V for connections to Power over Coax (PoC). Buck2 and Buck3 are two second stage converters and powered from the output of Buck1. All three buck converters operate in Forced-CCM mode with 2.1MHz switching frequency and optional Frequency Spread Spectrum (FSS) function for EMI mitigation. The output voltages are pre-programmed, which saves external feedback divider and minimizes system solution.
LDO4 is a high PSRR, low noise LDO designed for analog power rail. LDO5 is a general LDO with a separate voltage input pin for flexible configuration. Both LDO4 and LDO5 have pre-programmed output voltage and provide a continuous output current of up to 300mA.
The SCT61250S integrates protection features including programmable input under-voltage protection, input over-voltage protection, output over-voltage/under-voltage protection, over-current protection and thermal shutdown.
The SCT61250S is designed to support functional safety system up to ASIL-B. Build-in Self-Test (BIST) is integrated to diagnose over internal circuits. All critical comparators and register data will be checked during power-up stage.
With a compact 3mm×3mm TQFN-20L package, the SCT61250S greatly reduces external components count and PCB space.
