description
The TPS2014 and TPS2015 power distribution switches are intended for applications where heavy capacitive
loads and short circuits are likely to be encountered. The high-side switch is a 95-mΩ n-channel MOSFET. The
switch is controlled by a logic enable that is compatible with 3-V and 5-V logic. Gate drive is provided by an
internal charge pump designed to control the power switch rise times and fall times to minimize current surges
during switching. The charge pump requires no external components and allows operation from supplies as low
as 4 V.
When the output load exceeds the current-limit threshold or a short is present, the TPS20xx limits the output
current to a safe level by switching into a constant-current mode, and the overcurrent logic output is set to low.
Continuous heavy overloads and short circuits will increase the power dissipation in the switch and cause the
junction temperature to rise. A thermal protection circuit is implemented, which shuts the switch off to prevent
damage when the junction temperature exceeds its thermal limit. An undervoltage lockout is provided to ensure
the switch is in the off state at start-up.
The TPS2014 and TPS2015 differ only in short-circuit current limits. The TPS2014 is designed to limit at 1.2 A
load and the TPS2015 limits at 2 A (see the available options table). The TPS20xx is available in 8-pin
small-outline integrated circuit (SOIC) and 8-pin PDIP packages, and operates over a junction temperature
range of 0°C to 125°C.
