TLE8108EMXUMA1

Product Overview

The Infineon Technologies TLE8108EMXUMA1 is a surface-mount power driver intended for low-side switching of relay and solenoid loads. The device provides eight N-channel outputs with a 1:2 input-to-output ratio and SPI control, operating from a 4.5 V to 5.5 V load range. It comes in a 24-LSSOP exposed-pad package and includes open-load detection and over-temperature protection.

Key Features

• Eight low-side N-channel outputs for relay and solenoid driver applications
• SPI interface with 1:2 input-to-output ratio
• 400 mA maximum output current and 800 mOhm typical Rds On
• Open-load detection and over-temperature fault protection
• Operating junction temperature range of -40°C to 150°C
• Surface-mount PG-SSOP-24 package with exposed pad

Applications

• Relay and solenoid control in embedded systems
• SPI-managed switching of multiple 4.5 V to 5.5 V loads
• Open-load and over-temperature protected low-side output switching

Design & Procurement Notes

For design and procurement planning, confirm that the PG-SSOP-24 surface-mount package and SPI interface fit the board layout and controller resources. Verify that loads remain within the 400 mA output current rating and 4.5 V to 5.5 V load range. The 800 mOhm typical Rds On should be considered for conduction loss and thermal budgeting, especially with the exposed-pad package. Open-load detection and over-temperature protection can monitor relay or solenoid outputs, while the -40°C to 150°C junction temperature range defines the thermal operating envelope.
