VN5770AK-E
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 VIPower™ M0-5 Technology, while the low side switches are fully protected Table 1.
Key Features
- 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 VIPower™ 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. *
