THE PRODUCTS DESCRIBED HEREIN AND THIS DOCUMENTARE SUBJECT TO SPECIFIC DISCLAIMERS, SET FORTH AT Low Leakage and Quiescent Current, 1 A Load Switch with Reverse BlockingDESCRIPTIONThe SiP32431 is an Ultra low Leakage and Quiescent currentslew rate controlled high side switch with reverse blockingcapability. The switch is of a low ON resistance p-channelMOSFET that supports continuous current up to 1 A. The SiP32431 operates with an input voltage from V V. The SiP32431 features low input logic level to interface withlow control voltage from microprocessors. This device has avery low operating current , typically 10 pA at V SiP32431 is available in lead (Pb)-free package optionsincluding 6 pin SC70-6, and 4 pin TDFN4 mm x mmDFN4 packages.

2 The operation temperature range isspecified from -40 C to +85 C. The SiP32431 compact package options, operation voltagerange, and low operating current make it a good fit forbattery power V to V input voltage range No bias power rail required Low on-resistance RDS(on),typically 105 m at 5 V and 135 m at 3 Vfor TDFN4 mm x mm package Typical 147 m at 5 V and 178 m at 3 V forSC70-6 package Slew rate controlled turn-on time: 100 s Ultra low Leakage and Quiescent current :- VIN Quiescent current = nA- VIN shutdown Leakage = nA Reverse blocking capability SC70-6 and TDFN4 mm x mm packages Material categorization: for definitions of complianceplease see Wireless sensor network Smart meters Wearable Internet of things Portable medical devices Security systems Battery powered devices Portable InstrumentsTYPICAL APPLICATION CIRCUIT Fig.
