1 / 113 page  FS5502 High voltage PMIC with multiple SMPS and LDO Rev. 4 — 27 October 2021 Product data sheet 1 General description This device family is part of a global platform including FS5502/VR5500 (Quality Management), FS84 (fit for ASIL B) and FS85 (fit for ASIL D), pin to pin and software compatible. This data sheet covers FS5502 device only. The FS5502 is an automotive high voltage multi-output power supply integrated circuit, with focus on radio and radar applications. It includes multiple switch mode and linear voltage regulators. It offers external frequency synchronization input and output, for optimized system EMC performance and it is qualified in compliance with AEC-Q100 rev H (Grade1, MSL3). Several device versions are available, offering choice in number of output rails, output voltage setting, operating frequency and power up sequencing, to address multiple applications. 2 Features and benefits • 60 V DC maximum input voltage for 12 V and 24 V applications • VPRE synchronous buck controller with external MOSFETs. Configurable output voltage, switching frequency, and current capability up to 10 A peak. • Low voltage integrated synchronous BUCK1 converter, dedicated to MCU core supply with SVS capability. Configurable output voltage and current capability up to 3.6 A peak. • Low voltage integrated synchronous BUCK3 converter. Configurable output voltage and current capability up to 3.6 A peak. • EMC optimization techniques including SMPS frequency synchronization, spread spectrum, slew rate control, manual frequency tuning • One linear voltage regulator for MCU IOs and ADC supply, external physical layer. Configurable output voltage and current capability up to 400 mA DC. • OFF mode with very low sleep current (10 μA typ) • Two input pins for wake-up detection and battery voltage sensing • Device control via I2C interface with CRC • Power synchronization pin to operate two FS5502 devices or FS5502 plus an external PMIC • Three voltage monitoring circuits, dedicated interface for MCU monitoring, power good, reset and interrupt outputs • Configuration by OTP programming. Prototype enablement to support custom setting during project development in engineering mode. |
