1. Main Types of STMicroelectronics Power Management ICs

(1) Automotive-Grade Power Management ICs

SPSB100: Integrates 3 synchronous buck converters + 2 LDOs, supports AEC-Q100 certification, suitable for ADAS, body control modules (BCM), and other in-vehicle systems.

STPMIC25: Specifically designed for STM32MP2 microprocessors, integrating 7 DC/DC buck converters + 9 LDOs, supporting DDR3/DDR4 power supply, and compliant with ISO 26262 functional safety standards.

(2) Multi-channel PMIC (Power Management Integrated Circuit)

L6726A/L6727/L6728/L6728A: High-integration PWM controllers suitable for servers, PC motherboards, and POL (point-of-load) power supplies, supporting a wide input range of 1.5V to 18V and integrated MOSFET drivers.

(3) Buck/Boost Converters (DC-DC)

High-efficiency synchronous buck converters: e.g., ST1PS01, suitable for low-power IoT devices, supporting conversion efficiency of over 95%.  

Boost controllers: e.g., STBC08, used in battery-powered devices, supporting startup as low as 0.8V.

(4) Linear Regulator (LDO)  

Low Dropout LDO: e.g., LD39050, ultra-low noise (<30µV RMS), suitable for RF and precision analogue circuits.  

Automotive-grade LDO: e.g., L7987, compliant with AEC-Q100, used for ECU and sensor power supply.

(5) Battery Management ICs  

Charging Management Chips: e.g., STBC21, supporting USB Type-C PD fast charging, suitable for portable devices.  

Battery Level Monitoring ICs: e.g., STC3100, providing high-precision battery SOC (State of Charge) monitoring.
