JW7115/JW7115-1/JW7115-2/JW7111
50mΩ, Single
Power Switch with Flag
Parameters Subject to Change Without Notice
DESCRIPTION
The JW
®
7115/JW7115-1/JW7115-2/JW7111 is a
single channel current-limited power switch
optimized for Universal Serial Bus (USB) and
other hot-swap applications. The rise and fall
times are controlled to minimize current
overshoot or undershoot during switches on/off.
The device has fast short-circuit response time for
improved overall system robustness. It provides a
complete
protection
solution,
such
as
over-current
protection,
over-temperature
protection and short-circuit protection, as well as
controlled rise time and under-voltage lockout
function. A7.5ms de-glitch time on the open-drain
Flag output prevents false over-current reporting.
JW7115/JW7115-1/JW7115-2 offers SOT23-5
package.JW7111 offers both DFN2X2-6 and
SOT23-6 packages.
Company’s Logo is Protected, “JW” and “JOULWATT” are Registered
Trademarks of JoulWatt technology Inc.

Pulse-testing techniques maintain junction temperature close to ambient temperature; thermal effects must be taken
into account separately.
The discharge function is active when the device is disabled (when enable is de-asserted or during power-up
power-down when VIN< VUVLO).The discharge function offers a resistive discharge path for the external storage
capacitor for limited time.
