VN771K-E QUAD SMART POWER SOLID STATE RELAY FOR COMPLETE H BRIDGE CONFIGURATIONS Table 1. General Features Figure 1. Package Type R I V DS(on) OUT CC VN771K-E 95m (*) 9A (**) 36V Note: (*) Total resistance of one side in bridge configuration. Note: (**) Typical current limitation value. SUITED AS LOW VOLTAGE BRIDGE LINEAR CURRENT LIMITATION VERY LOW STAND-BY POWER DISSIPATION SHORT CIRCUIT PROTECTED STATUS FLAG DIAGNOSTIC (OPEN DRAIN) SO-28 INTEGRATED CLAMPING CIRCUITS UNDERVOLTAGE PROTECTION ESD PROTECTION IN COMPLIANCE WITH THE 2002/95/EC EUROPEAN DIRECTIVE The dual high side switches have built-in thermal shutdown to protect the chips from DESCRIPTION overtemperature and current limiter blocks to The VN771K-E is a device formed by three protect the device from short circuit. Status output is provided to indicate open load in off and on state monolithic chips housed in a standard SO-28 and overtemperature. The low side switches are package: a double high side and two low side switches. Both the double high side and low side two OMNIFET II types (fully autoprotected Power MOSFET in VIPower technology). They have switches are made using STMicroelectronics built-in thermal shutdown, linear current limitation VIPower M0-3 Technology. This device is suitable to drive a DC motor in a bridge and overvoltage clamping. Fault feedback for thermal intervention can be detected by configuration as well as to be used as a quad switch for any low voltage application. monitoring the voltage at the input pin. Table 2.
