ISO HIGH SIDE SMART POWER SOLID STATE RELAY REV. 2 Table 1. General Features produces a voltage drop of 0.5 V.
DESCRIPTION
The VN21 is a monolithic device made using STMicroelectronics VIPower Technology, intended for driving resistive or inductive loads with one side grounded. Built-in thermal shut-down protects the chip from over temperature and short circuit. The open drain diagnostic output indicates: open load in off state and in on state, output shorted to V CC and overtemperature. Fast demagnetization of inductive loads is achieved by negative (-18V) load voltage at turn-off. Note: 2. The maximum continuous output current is the current at Tc = 85 °C for a battery voltage of 13 V which does not activate self protection Figure 1. Package Table 2. Order Codes
