With the introduction of the TLE 8209-2SA, we are addressing the growing need for H-bridges in powertrain applications.
TLE 8209-2SA is targeted specifically at electronic throttle control systems but is also suitable for other DC motor applications like exhaust gas recirculation systems, variable valve controls and turbochargers featuring variable geometries.
The new powertrain H-bridge comes in the well-established 430 mil power DS0-20 package. It contains all features required for safe operation even in harsh environmental conditions. These include Vdd monitoring for a safe switch-off path in case of Vdd loss or overvoltage and 18V-tolerant I/Os for an increased level of safety and robustness. During extreme thermal conditions, for junction temperatures above 165°C, the temperature-dependent current reduction feature reduces the current automatically for added safety and reliability.
The power MOSFETs of the output stages are optimized for low electromagnetic emission. Designers are also free to choose between two diferent slew rates. EMI measurements confirm that the TLE 8209-2SA shows outstanding EMC behaviour!
