The SiP32501 is a compact, low RON turn on slew rate controlled load switch. The device has 66 m resistance and operates over the input voltage range of 0.9 V to 2.5 V without requirement of extra bias power rail. The SiP32501 has low input logic control threshold that can interface with low voltage control GPIO directly without extra level shift or driver. The switch supports designs when control logic voltage is higher than input power voltage. There is a pull down at this EN logic control pin. The SiP32501 has 20 μs typically for input voltage of 1.2 V. Its turn off delay time is less than 1 μs. An output discharge switch is integrated. SiP32501 is available in small TDFN4 package of 1.2 mm x 1.6 mm x 0.55 mm. The device is designed for the operation temperature range of -40 °C to +85 °C.
