description
The TPS201x family of power-distribution switches is intended for applications where heavy capacitive loads
and short circuits are likely to be encountered. The high-side switch is a 95-m
N-channel MOSFET. Gate drive
is provided by an internal driver and charge pump designed to control the power switch rise times and fall times
to minimize current surges during switching. The charge pump operates at 100 kHz, requires no external
components, and allows operation from supplies as low as 2.7 V. When the output load exceeds the current-limit
threshold or a short circuit is present, the TPS201x limits the output current to a safe level by switching into a
constant-current mode. Continuous heavy overloads and short circuits increase power dissipation in the switch
and cause the junction temperature to rise. If the junction temperature reaches approximately 180
°C, a thermal
protection circuit shuts the switch off to prevent damage. Recovery from thermal shutdown is automatic once
the device has cooled sufficiently.
The members of the TPS201x family differ only in short-circuit current threshold. The TPS2010 is designed to
limit at 0.4-A load; the other members of the family limit at 1.2 A, 2 A, and 2.6 A (see the available options table).
The TPS201x family is available in 8-pin small-outline integrated circuit (SOIC) and 14-pin thin shink
small-outline (TSSOP) packages and operates over a junction temperature range of – 40
°C to 125°C. Versions
in the 8-pin SOIC package are drop-in replacements for Siliconix’s Littlefoot
power PMOS switches, except
that GND must be connected.
