In 2026, the Power Management IC (PMIC) could be the "busiest" category in the entire semiconductor industry. AI servers are racing for it—the power consumption of a single AI server has surged to 30-100 kW, with power semiconductor consumption more than three times that of traditional servers; New Energy Vehicles (NEVs) are racing for it—the chip value per vehicle has risen to 4,500 RMB, and China's NEV penetration rate is approaching 50%; consequently, energy storage, fast charging, and industrial automation are also in the rush. Reports indicate that the global Power Management IC market will reach $44.43 billion this year; the Chinese market alone is sized at 159 billion RMB, yet supply cannot keep pace with demand.
Price is the best barometer. Texas Instruments raised its PMIC quotes for the third time this year on July 1, followed by Infineon and STMicroelectronics; domestic players like Injoinic and Maxic Technology took the lead in raising prices by 10%-20% in the first quarter. The wafer foundry segment is also under simultaneous pressure—prices for 8-inch mature process nodes have increased by 5%-20%, and the new PMIC tape-out volume for AI servers alone will consume 3%-4% of the global 8-inch capacity share. An industry insider joked: PMICs are transforming from "supporting roles" into a new "choke point" battlefield.
In this new battlefield, what are the key domestic forces? In the selection for the 2026 "Hardcore Power Management IC Award", four shortlisted companies are honing their capabilities on this most challenging frontier.

WSCH4100STCP The WSCH4100S series uniformly adopts the compact ESOP-8L package and single-channel independent design, perfectly adapting to multi-scenario load protection and control. It integrates three protection functions at the on-chip hardware level without software intervention: ① Overcurrent protection: Automatically limits current or shuts down when the output current exceeds the threshold. ② Over-temperature protection: Hardware shuts down when the junction temperature rises abnormally, with self-recovery after cooling. ③ Short-circuit protection: Microsecond-level response to cut off when the output is shorted to ground. The three work synergistically to control faults within the chip at the first moment, without affecting downstream circuits.
Furthermore, during overcurrent or over-temperature events, it proactively outputs status signals to the MCU (Microcontroller Unit) via the diagnostic pin. The system can record faults and execute protection strategies accordingly to achieve closed-loop management.
This chip primarily serves the two-wheeler market, providing hardware-level protection for the whole vehicle power protection solution, saving peripheral components and reducing costs.
