Mingjiada Electronics supplies TLE8108EM, an 8-channel low-end switch designed for automotive powertrain applications with an integrated serial peripheral interface (SPI) to support precise load control and diagnostics for relay driver, motor control, LED driver and other scenarios.
TLE8108EM Product Overview and Core Features
The TLE8108EM is a high-performance 8-channel low-side switch from Infineon Technologies in a PG-SSOP-24 package with an operating temperature range from -40°C to 150°C and fully compliant with automotive AEC-Q100.13 The device is particularly suited for harsh automotive environments, such as engine management systems, transmission control units, and body electronics modules.
The core strength of the TLE8108EM lies in its highly integrated design concept:
8-channel independent control: TLE8108EM has a maximum output current of 400mA per channel and a typical on-resistance of only 800mΩ (max. 1.7Ω), which effectively reduces power loss.
16-bit SPI interface: TLE8108EM enables precise channel control and comprehensive diagnostic feedback, supports daisy-chain connection and is compatible with 8-bit SPI devices.
4 direct PWM inputs: the TLE8108EM provides flexible hardware control options, enabling basic switching functions without SPI intervention.
Multiple Protection Mechanisms: The TLE8108EM includes over-current protection (auto shutdown), over-temperature protection, active clamp circuitry (for driving inductive loads), and ESD protection.
Comprehensive diagnostic functions: TLE8108EM can monitor short circuit to ground (SCG), open load (OL) and short circuit to battery (SCB) fault status in real time via SPI.
The TLE8108EM's low quiescent current standby mode makes it particularly suitable for power-sensitive automotive electronics applications, and is RoHS compliant, making it a truly ‘green product’.
TLE8108EM Technical Parameters
The TLE8108EM is supplied by Mingjiaoda Electronics with the following key electrical parameters:
Supply voltage range: 4.5V to 5.5V, perfect for automotive 5V systems.
Output characteristics: 400mA continuous current capability per channel, higher peak current capability.
Switching speed: Typical turn-on time of 50μs, turn-off time of 50μs, meeting the response requirements of most automotive actuators.
Operating temperature: -40°C to +150°C junction temperature range, ensuring reliability in extreme environments
Package: PG-SSOP-24 with exposed pads for optimised thermal performance
The TLE8108EM uses monolithic integration technology with an internal integrated power n-MOSFET switch, eliminating the need for an external driver circuit and significantly simplifying system design. Its innovative active clamp circuit can effectively suppress the reverse electromotive force generated when switching inductive loads (e.g. relays, solenoids) and protect the switching tubes from voltage spike damage.
TLE8108EM Application Areas
Target applications for the TLE8108EM include, but are not limited to:
Automotive electronics: engine management units, transmission control modules, body control modules, lighting systems, seat/window/door lock actuation, etc.
Industrial control: PLC output modules, industrial relay drivers, solenoid valve control, LED lighting drivers, etc.
Home appliances and consumer electronics: motor control in white goods, actuator drive in smart home, etc.
TLE8108EM is especially suitable for application scenarios that require high-density drives, such as automotive central body controllers driving multiple relays, LED light clusters, or small motors at the same time.
