3 Description
The TPS1641x is an integrated eFuse with accurate
power limit or current limit. The device provides robust
protection with integrated overcurrent protection,
overvoltage protection, IN to OUT short detection and
overtemperature protection.
TPS16410 and TPS16411 devices provide ±5%
power limiting at 15 W for loads and it also provides
configurable blanking time for transient overload or
overcurrent events. TPS16410 and TPS16411 can be
used for low power circuits (LPCs) for 15-W power
limiting as per IEC60335 and UL60730 standards.
TPS1641x devices provide protection from adjacent
pin short and pin short to GND faults.
Applications such as backplane power protection in
PLC and DCS modules configure the current limit with
a resistor on the ILIM pin. TPS16412 and TPS16413
devices provide ±6% current limiting at 1 A for loads
and these devices also provide output slew rate
control with dVdT pin to charge large capacitive loads
at power up.
TPS1641x features IN to OUT short detection. The
device indicates IN to OUT short on the FLT pin. The
FLT pin can be either provided to MCU as digital input
or it can be used to drive an external PFET.
The devices are characterized for operation over a
junction temperature range of –40°C to +125°C.
