Vishay Siliconix
1.0 A Slew Rate Controlled Load Switch with Reverse Blocking in SC70-6, and TDFN4 1.2 mm x 1.6 mm
DESCRIPTION
The SiP32431 is a slew rate controlled high side switch with reverse blocking capability. The switch is of a low ON resistance p-channel MOSFET that supports continuous current up to 1.0 A. The SiP32431 operates with an input voltage from 1.5 V to 5.5 V. The SiP32431 features low input logic level to interface with low control voltage from microprocessors. This device has a very low operating current, typically 50 pA. The SiP32431 is available in lead (Pb)-free package options including 6 pin SC70-6, and 4 pin TDFN4 1.2 mm x 1.6 mm DFN4 packages. The operation temperature range is specified from - 40 °C to + 85 °C. The SiP32431 compact package options, operation voltage range, and low operating current make it a good fit for battery power applications.
FEATURES
• 1.5 V to 5.5 V input voltage range • Very low RDS(on), typically 105 m at 5 V and 135 m at 3 V for TDFN4 1.2 mm x 1.6 mm package • Typical 147 m at 5 V and 178 m at 3 V for SC70-6 package • Slew rate controlled turn-on time: 100 µs • Low quiescent current < 1 µA • Low shutdown current < 1 µA • Reverse blocking capability • SC70-6 and TDFN4 1.2 mm x 1.6 mm packages • Compliant to RoHS Directive 2002/95/EC • Halogen-free according to IEC 61249-2-21 definition
