Product Overview

The VNI2140J is a dual high side smart power Solid State Relay designed using STMicroelectronics VIPower technology. The device drives two independent resistive or inductive loads with one side connected to ground. Active current limitation prevents a drop in system power supply in cases of shorted-load and built-in thermal shutdown protects the chip from damage due to over-temperature and short-circuits. In overload conditions channel turns OFF and ON automatically to maintain the junction temperature between TTSD and TR. If the case temperature reaches TCSD, the over-loaded channel is turned OFF and restarts only when case temperature decreases down to TCR. In order to avoid high-peak current from the supply, when more than one channel is over-loaded the TCSD restart is not simultaneous. Non over-loaded channels continue to operate normally. The open-drain diagnostics output indicates over-temperature conditions and open-load in OFF state.
  • Shorted load protections
  • Junction over-temperature protection
  • Protection against loss of ground
  • Under-voltage shutdown
  • Open load in OFF-state and short to VCC detection
  • Open-drain diagnostic outputs
  • 3.3V CMOS/TTL compatible inputs
  • Fast demagnetization of inductive loads
