VN31SP ® HIGH SIDE SMART POWER SOLID STATE RELAY TYPE V DSS R DS(on) I n(*) V CC VN31SP 60 V 0.03 Ω 11.5 A 26 V ■ ■ ■ ■ ■ ■ ■ MAXIMUM CONTINUOUS OUTPUT CURRENT (#):31 A @ Tc=85oC 5 V LOGIC LEVEL COMPATIBLE INPUT THERMAL SHUT-DOWN UNDER VOLTAGE PROTECTION OPEN DRAIN DIAGNOSTIC OUTPUT INDUCTIVE LOAD FAST DEMAGNETIZATION VERY LOW STAND-BY POWER DISSIPATION DESCRIPTION The VN31SP 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 BLOCK DIAGRAM 10 1 PowerSO-10 VCC and overtemperature. Fast demagnetization of inductive loads is archivied by negative (-18V) load voltage at turn-off. (*) In = Nominal current according to ISO definition for high side automotive switch (see note 1) (#) The maximum continuous output current is the the current at Tc = 85 oC for a battery voltage of 13V which does not activate self protection.

The truth table shows input, diagnostic and output voltage level in normal operation and in fault conditions. The output signals are processed by internal logic. The open load diagnostic output has a 5 ms filtering. The filter gives a continuous signal for the fault condition after an initial delay of about 5 ms. This means that a disconnection during normal operation, with a duration of less than 5 ms does not affect the status output. Equally, any re-connection of less than 5 ms during a disconnection duration does not affect the status output. No delay occur for the status to go low in case of overtemperature conditions. From the falling edge of the input signal the status output initially low in fault condition (over temperature or open load) will go back with a delay (tpovl)in case of overtemperature condition and a delay (tpol) in case of open load. These feature fully comply with International Standard Office (I.S.O.) requirement for automotive High Side Driver. To protect the device against short circuit and over current conditions, the thermal protection turns the integrated Power MOS off at a minimum junction temperature of 140 oC. When the temperature returns to 125 oC the switch is automatically turned on again. In short circuit the protection reacts with virtually no delay, the sensor being located in the region of the die where the heat is generated. Driving inductive loads, an internal function of the device ensures the fast demagnetization with a typical voltage (Vdemag) of -18V. This function allows to greatly reduce the power dissipation according to the formula: Pdem = 0.5 • Lload • (Iload)2• [(VCC+Vdemag)/Vdemag] •f where f = switching frequency and Vdemag = demagnetization voltage Based on this formula it is possible to know the value of inductance and/or current to avoid a thermal shut-down. The maximum inductance which causes the chip temperature to reach the shut down temperature in a specific thermal environment, is infact a function of the load current for a fixed VCC, Vdemag and f. PROTECTING THE DEVICE AGAIST LOAD DUMP - TEST PULSE 5 The device is able to withstand the test pulse No. 5 at level II (Vs = 46.5V) according to the ISO T/R 7637/1 without any external component. This means that all functions of the device are performed as designed after exposure to disturbance at level II. The VN06SP is able to withstand the test pulse No.5 at level III adding an external resistor of 150 ohm between GND pin and ground plus a filter capacitor of 1000 µF between VCC pin and ground (if RLOAD ≤ 20 Ω). 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 GND pin 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 increa- sed 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 [6] (see application circuit in fig. 4), which becomes the common signal GND for the whole control board avoiding shift of Vih, Vil and Vstat. This solution allows the use of a standard diode. 5/9 VN31SP TRUTH TABLE INPUT OUTPUT DIAGNOSTIC Normal Operation L H L H H H Open Circuit (No Load) H H L Over-temperature H L L Under-voltage X L H Short load to V CC L H L Figure 1: Waveforms Figure 2: Over Current Test Circuit 6/9 VN31SP Figure 3: Typical Application Circuit With A Schottky Diode For Reverse Supply Protection Figure 4: Typical Application Circuit With Separate Signal Ground 7/9 VN31SP PowerSO-10 MECHANICAL DATA mm DIM.
