Using real-time, closed-loop thermal management algorithms, the TS5111 sensor from Renesas helps DDR5 memory modules run at peak efficiency.

Using real-time, closed-loop thermal management algorithms, the TS5111 temperature sensor from Renesas helps DDR5 memory modules run at peak efficiency. The JEDEC-compliant sensor is also useful for other temperature-sensitive applications, such as solid-state drives, motherboards, and communication equipment.

The TS5111 sensor achieves typical measurement accuracy of 0.5°C from 75°C to 95°C, while providing programmable warning flags that enable systems to exercise thermal control-loop mechanisms like memory refresh rates, fan speeds, and bandwidth throttling. It offers a two-wire bus serial interface that supports I2C and I3C protocols at data transfer rates of up to 12.5 MHz. Other device functions include packet-error and parity-error checking, bus reset, and in-band interrupt.

Housed in a 6-ball WLCSP with dimensions of just 0.80×1.30×0.50 mm, the TS5111 is well-suited for systems with small form factors. The part requires a single 1.8 V or optionally 1.0 V power supply input and operates over a temperature range of -40°C to +85°C.

Part of a series of DDR5 devices, including a registered clock driver, power management IC, and SPD (serial presence detect) hub, the TS5111 temperature sensor is sampling now to qualified customers.
