The VN771K is a low voltage bridge-type quad smart power solid state relay from STMicroelectronics, which features linear current limiting, very low standby power dissipation, short circuit protection, status flag diagnostics (open drain), integrated clamping circuits, undervoltage protection and ESD protection.
The VN771K is a device formed by three monolithic chips housed in a standard SO-28 package. It consists of a double high side switch and two low side switches, both utilizing STMicroelectronics viPower™ MO-3 Technology. The device is suitable for driving DC motors in bridge configurations or as a quad switch for various low voltage applications.
| Package | SO-28 |
|---|---|
| Total resistance of one side in bridge configuration | 95 mΩ |
| Typical current limitation value | 9 A |
The device internally limits the DC output current, but it can handle a reverse DC output current of up to 6 A.
The case operating temperature range is from -40 to 150 °C.
The thermal resistance junction-case for the high side switch is 20 °C/W.
