Figure 30. Typical Hot-Plug Implementation
By placing the TPS206x between the VCC input and the rest of the circuitry, the input power reaches these
devices first after insertion. The typical rise time of the switch is approximately 1 ms, providing a slow voltage
ramp at the output of the device. This implementation controls system surge currents and provides a
hot-plugging mechanism for any device.
DETAILED DESCRIPTION
Power Switch
The power switch is an N-channel MOSFET with a low on-state resistance. Configured as a high-side switch, the
power switch prevents current flow from OUT to IN and IN to OUT when disabled. The power switch supplies a
minimum current of 1 A.
Charge Pump
An internal charge pump supplies power to the driver circuit and provides the necessary voltage to pull the gate
of the MOSFET above the source. The charge pump operates from input voltages as low as 2.7 V and requires
little supply current.
Driver
The driver controls the gate voltage of the power switch. To limit large current surges and reduce the associated
electromagnetic interference (EMI) produced, the driver incorporates circuitry that controls the rise times and fall
times of the output voltage.
Enable (ENx or ENx)
The logic enable disables the power switch and the bias for the charge pump, driver, and other circuitry to reduce
the supply current. The supply current is reduced to less than 1
μA when a logic high is present on ENx, or when
a logic low is present on ENx. A logic zero input on ENx, or a logic high input on ENx restores bias to the drive
and control circuits and turns the switch on. The enable input is compatible with both TTL and CMOS logic
levels.
Overcurrent (OCx)
The OCx open-drain output is asserted (active low) when an overcurrent or overtemperature condition is
encountered. The output remains asserted until the overcurrent or overtemperature condition is removed. A
10-ms deglitch circuit prevents the OCx signal from oscillation or false triggering. If an overtemperature shutdown
occurs, the OCx is asserted instantaneously.
