The VNH5050 is available in a much smaller package. Typical applications ST sees for this component are door lock and sunroof H-bridge applications. The PWM can do up to 20kHz. Compared to the larger packaged devices it does not have the cross conduction issues. This configuration comes in two flavors: a 50mOhm device and 180mOhm device. The part numbers reflect their 25°C Rds(on) per leg values. The VNH5050A is a 50mOhm/leg device and the VNH5180A is a 180mOhm/leg device. The VNH5050 is specified to have a 30A current limit while the VNH5180 is specified to have a 8A current limit. One of the interesting things about this package is the source of the high-sides and the drain of the low-sides are not connected. The input configuration limits to driving either one leg high and the other leg low or the one leg low and the other leg high. The device cannot drive one switch high and the other switch low on the same “side” at the same time (this is due to the cross conduction protection). They can be used as independent lows or independent high side switches. As long as they are mutually exclusive, this can be done. These devices have analog current sense diagnostics for the high-side. It has active power limitation, thermal shutdown protection and the outputs are protected against shorts to ground and VCC.
