| VN5770AK-E Quad smart power solid state relay for complete H bridge configurations Features Type VN5770AK-E RDS(on) 280m(1) IOUT 8.5A(2) VCC 36V SO-28 1. Total resistance of one side in bridge configuration 2. Typical current limitation value General features - Inrush current management by active power limitation on the high side switches - Very low stand-by current - Very low electromagnetic susceptibility - In compliance with the 2002/95/EC European directive Protection - High side drivers undervoltage shutdown - Overvoltage clamp - Output current limitation - High and low side overtemperature shutdown - Short circuit protection - ESD protection Diagnostic functions - Proportional load current sense - Thermal shutdown indication on both the high and low side switches VIPowerTM M0-3 OMNIFET II. This device is suitable to drive a DC motor in a bridge configuration as well as to be used as a quad switch for any low voltage application. The dual high side switches integrate built-in nonlatching thermal shutdown with thermal hysteresis. An output current limiter protects the device in overload condition. In the case of long overload duration, the device limits the dissipated power to a safe level up to thermal shut-down intervention. An analog current sense pin delivers a current proportional to the load current (according to a known ratio) and indicates overtemperature shutdown of the relevant high side switch through a voltage flag. The low side switches have built-in non-latching thermal shutdown with thermal hysteresis, linear current limitation and overvoltage clamping. Fault feedback for overtemperature shutdown of the low side switch is indicated by the relevant input pin current consumption going up to the fault sink current flag. Description The VN5770AK-E is a device formed by three monolithic chips housed in a standard SO-28 package: a double high side and two low side switches. The double high side is made using STMicroelectronics VIPowerTM M0-5 Technology, while the low side switches are fully protected Table 1.

This diode prevents a reverse current flow back to Vbatt in case the bridge gets disabled via the logic inputs while motor inductance still carries energy. In order to prevent a hazardous overvoltage at circuit supply terminal (Vcc), a blocking capacitor (C) is needed to limit the voltage overshoot. As basic orientation, 50F per 1A load current in recommended. In alternative, also a Zener protection (Z) is suitable. Even if a reverse polarity diode is not present, it is recommended to use a capacitor or zener at Vcc because a similar problem appears in case supply terminal of the module has intermittent electrical contact to the battery or gets disconnected while motor is operating.
