2 / 9 page ST890 2/9 Table 2: Absolute Maximum Ratings Absolute Maximum Ratings are those values beyond which damage to the device may occur. Functional operation under these condition is not implied. Table 3: Thermal Data (*) This value depends from thermal design of PCB on which the device is mounted. Table 4: Truth Table For ON/OFF Switch Figure 2: Pin Connection (top view) Table 5: Pin Description Symbol Parameter Value Unit VI Supply Voltage -0.5 to 6 V VON Input Voltage at ON pin -0.5 to 6 V VFAULT_N Input Voltage at FAULT_N pin -0.5 to 6 V VSET Voltage at SET pin -0.5 to (VIN + 0.5) V IDS Maximum Continuous Switching Current 1.5 A Tstg Storage Temperature Range -65 to +150 °C Top Operating Junction Temperature Range (C series) (B series) 0 to +70 -40 to +85 °C °C Symbol Parameter SO-8 Unit Rthj-amb Thermal Resistance Junction-ambient (*) 160 °C/W ON/OFF OUT LON HOFF FAULT FLAG H Normal Operation L Fault Condition Pin N° Symbol Name and Function 1, 2 IN Input P-Channel MOSFET source. Bypass IN with a 1 µF capacitor to ground. 3ON Active Low Switch On Input. A logic low turns the switch ON 4 GND Ground 5 SET Set Current Limit Input. A resistor from SET to GROUND sets the current limit for the switch. RSET=1.38x10 3/I LIM, where ILIM is the desired current limit in Amperes 6, 7 OUT Switch Output. P-Channel MOSFET drain. Bypass OUT with a 0.1µF capacitor to GROUND. 8FAULT Fault Indicator Output. This open drain output goes low when in current limit or when the die temperature exceeds 135°C |
