SIP4282

www.DataSheet4U.com New Product SiP4282 Vishay Siliconix 1 A Slew Rate Controlled Load Switch in PPAK SC75-6 DESCRIPTION The SiP4282 is a P-Channel MOSFET power switch IC designed for high-side load switching applications. The output switching transistor is a P-Channel MOSFET device that has a 140 mΩ RDS(ON) typically to increase load switching power handling capacity. The SiP4282 is available in two different versions with turn-on and turn-off characteristics ranging from very fast to slew rate limited. In addition to a fast turn-off time of 4 µs, the SiP4282-3 version offers a shutdown load discharge circuit to instantaneously turn off a load circuit when the switch is disabled. The SiP4282 load switch operates with an input voltage ranging from 1.8 V to 5.5 V, making it ideal for both 3 V and 5 V systems. The SiP4282 also features an under-voltage lock out which turns the switch off when an input undervoltage condition exists. Input logic levels are TTL and 2.5 V to 5 V CMOS compatible. This device has a very low operating current (typically 2.5 µA), making it ideal for battery-powered applications. In shutdown mode, the supply current decreases to less than 1 µA. The SiP4282 is available in a lead (Pb)-free 6 pin PPAK SC75-6 package and is specified over - 40 °C to 85 °C temperature range. FEATURES 1.8 V to 5.5 V Input Voltage range Very Low RDS(ON), typically 140 mΩ at 5 V and 175 mΩ at 3 V Slew rate limited turn-on time options - SiP4282-1: 1 ms - SiP4282-3: ...
