5 / 36 page Data Sheet 5 Rev. 1.0, 2008-10-30 TLE7234E Overview Detailed Description The TLE7234E is an eight channel high-side and low-side relay switch providing embedded protective functions. The output stages incorporate two low-side switches (0.9 Ω per channel), four high-side switches (two channels with 0.9 Ω and two channels with 1.6 Ω) and two auto-configuring high-side or low-side switches (0.9 Ω per channel). The auto-configuring switches can be utilized in high-side or low-side configuration just by connecting the load accordingly. They are also suitable to switch a 5 V supply line in high-side configuration. Protective and diagnostic functions adjust automatically to the chosen configuration. The 8 bit serial peripheral interface (SPI) is utilized for control and diagnosis of the device and the loads. The SPI interface provides daisy chain capability in order to assemble multiple devices in one SPI chain by using the same number of micro-controller pins. Furthermore, the TLE7234E is equipped with three input pins that can be individually routed to the output control of each channel thus offering complete flexibility in design and PCB-layout. The input multiplexer is controlled via SPI. The device provides full diagnosis of the load via open load, over load and short circuit detection. SPI diagnosis flags indicate latched fault conditions that may have occurred. Each output stage is protected against short circuit. In case of over load, the affected channel switches off. There are temperature sensors available for each channel to protect the device against over temperature. The device protects itself with a build in reverse polarity protection which prohibits intrinsic current flow through the logic during reverse polarity. However the output stages still incorporate a reverse diode where current can flow through during reverse polarity. The power transistors are built by N-channel power MOSFETs. The inputs are ground referenced CMOS compatible. The device is monolithically integrated in Smart Power Technology. |
