CURRENT-LIMITED, POWER-DISTRIBUTION SWITCHES
Output Discharge Function
70-m High-Side MOSFET
1-A Continuous Current
Thermal and Short-Circuit Protection
Accurate Current Limit
(1.1 A min, 1.9 A max)
Operating Range: 2.7 V to 5.5 V
The
TPS206x-1
power-distribution
switches
are
0.6-ms Typical Rise Time
intended for applications where heavy capacitive
Undervoltage Lockout
loads and short-circuits are likely to be encountered.
This device incorporates 70-m
N-channel MOSFET
Deglitched Fault Report (OC)
power switches for power-distribution systems that
No OC Glitch During Power Up
require multiple power switches in a single package.
1-A Maximum Standby Supply Current
Each switch is controlled by a logic enable input.
Ambient Temperature Range: -40°C to 85°C
Gate drive is provided by an internal charge pump
designed to control the power-switch rise times and
ESD Protection
fall times to minimize current surges during switching.
The charge pump requires no external components
and allows operation from supplies as low as 2.7 V.
Heavy Capacitive Loads
These switches provide a discharge function that
Short-Circuit Protections
provides a controlled discharge of the output voltage
stored on the output capacitor.
When the output load exceeds the current-limit threshold or a short is present, the device limits the output current
to a safe level by switching into a constant-current mode, pulling the overcurrent (OCx) logic output low. When
continuous heavy overloads and short-circuits increase the power dissipation in the switch, causing the junction
temperature to rise, a thermal protection circuit shuts off the switch to prevent damage. Recovery from a thermal
shutdown is automatic once the device has cooled sufficiently. Internal circuitry ensures that the switch remains
off until valid input voltage is present. This power-distribution switch is designed to set current limit at 1.5 A
typically.
