STMLS05ACQTR

Overview

The STMLS05ACQTR is an array of five PMOS load switches designed for power distribution in mobile and wearable electronics. It features a programmable I2C interface for channel control and soft-start timing, which mitigates high inrush currents. The device operates with input/output voltages from 1.05 V to 5.5 V and a VDD supply range of 1.8 V to 3.6 V. Key electrical parameters include a maximum rated output current of 100 mA per channel and a typical on-resistance (RON) of 120 mΩ at 1.8 V. Quiescent current is ultra-low, reaching a maximum of 2.4 µA when the I2C block is active. The component includes built-in output discharge circuitry, ESD tolerance of 2 kV HBM, and functions within a temperature range of -40 °C to 70 °C.

Feature Summary

Five-channel PMOS switch array with individual I2C control
Programmable soft-start timing to limit inrush current
Ultra-low quiescent current consumption
Integrated output discharge circuitry

Applications

Smart phones
Tablets
Mobile device accessories
Wearable devices

Procurement Notes

Verify the specific ordering suffix ACQTR against official documentation to confirm package type and reel specifications. Ensure compatibility with the required I2C base address 0x5C. Confirm that the UFQFPN 3x3 mm footprint matches the target PCB layout. Validate environmental compliance requirements such as lead-free and halogen-free status before finalizing procurement.

Selection Notes

Select this component when multiple independent power rails require controlled sequencing and low standby current. The I2C interface allows for dynamic configuration of soft-start times and enable states. Consider the 120 mΩ typical RON for voltage drop calculations under 100 mA loads. Verify that the system's VDD supply remains within the 1.8 V to 3.6 V range for proper UVLO operation.

Part Context

The STMLS05ACQTR belongs to the STMLS05 family of enhanced five-channel PMOS load switches manufactured by STMicroelectronics. This series is optimized for portable applications requiring efficient power management and space-saving solutions. The device integrates advanced protection features and flexible control interfaces within a compact 16-lead package.
