TECHNICAL DATA
Adjustable 1 Channel Current Limited Power Switch
Description
The KIC6961T is integrated power switches optimized for USB and other
hot-swap applications with a programmable current limit feature. Current
limit accuracy 6 % can be achieved at high current-limit settings.
The family of devices complies with USB 2.0 and is available with high
polarity of Enable input. They offer current and thermal limiting and short
circuit protection as well as controlled rise time and under-voltage lockout
functionality.

Applications Information
1. Supply Filtering
A 0.01uF to 0.1 F bypass capacitor from VIN to GND, located near the KIC6961T, is strongly recommended to control supply
transients. Without a bypass capacitor, an output short may cause sufficient ringing on the input (from supply lead inductance)
to damage internal control circuitry. Input transients must not exceed the absolute maximum supply voltage (VIN max = 6.5V)
even for a short duration.
2. Enable Input
VEN must be driven logic high for a clearly defined input. Floating the input may cause unpredictable operation. VEN should
not be allowed to go negative with respect to GND.
