| VN20N HIGH SIDE SMART POWER SOLID STATE RELAY TYPE VN20N s V DSS 60 V R DS( on) 0.05 I OUT 33 A VC C 26 V s s s s s OUTPUT CURRENT (CONTINUOUS): 33A @ Tc=25 oC 5V LOGIC LEVEL COMPATIBLE INPUT THERMAL SHUT-DOWN UNDER VOLTAGE SHUT-DOWN OPEN DRAIN DIAGNOSTIC OUTPUT VERY LOW STAND-BY POWER DISSIPATION PENTAWATT (vertical) PENTAWATT (horizontal) DESCRIPTION The VN20N is a monolithic device made using SGS-THOMSON Vertical Intelligent Power 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 input control is 5V logic level compatible. The open drain diagnostic output indicates open circuit (no load) and over temperature status.

FUNCTIONAL DESCRIPTION The device has a diagnostic output which indicates open circuit (no load) and over temperature conditions. The output signals are processed by internal logic. To protect the device against short circuit and over-current condition, the thermal protection turns the integrated Power MOS off at a minimum junction temperature of 140 oC. When the temperature returns to about 125 oC the switch is automatically turned on again. In short circuit conditions the protection reacts with virtually no delay, the sensor being located in the region of the die where the heat is generated. PROTECTING THE DEVICE AGAINST REVERSE BATTERY The simplest way to protect the device against a continuous reverse battery voltage (-26V) is to insert a Schottky diode between pin 1 (GND) and ground, as shown in the typical application circuit (fig. 3). The consequences of the voltage drop across this diode are as follows: - If the input is pulled to power GND, a negative voltage of -VF is seen by the device. (VIL, VIH thresholds and VSTAT are increased by VF with respect to power GND). - The undervoltage shutdown level is increased by VF . If there is no need for the control unit to handle external analog signals referred to the power GND, the best approach is to connect the reference potential of the control unit to node [1] (see application circuit in fig. 4), which becomes the common signal GND for the whole control board. In this way no shift of VIH, V IL and VSTAT takes place and no negative voltage appears on the INPUT pin; this solution allows the use of a standard diode, with a breakdown voltage able to handle any ISO normalized negative pulses that occours in the automotive environment. 4/11 VN20N TRUTH TABLE INPUT Normal Operation Open Circuit (No Load) Over-temperature Under-voltage L H H H X OUTPUT L H H L L DIAGNOSTIC H H L L H Figure 1: Waveforms Figure 2: Over Current Test Circuit 5/11 VN20N Figure 3: Typical Application Circuit With A Schottky Diode For Reverse Supply Protection Figure 4: Typical Application Circuit With Separate Signal Ground 6/11 VN20N RDS(on) vs Junction Temperature RDS(on) vs Supply Voltage RDS(on) vs Output Current Input voltages vs Junction Temperature Output Current Derating Open Load vs Junction Temperature 7/11 VN20N Pentawatt (vertical) MECHANICAL DATA DIM.
