3 Description
The TPS1641x family are integrated eFuse devices
with accurate power limit or current limit. The device
family provides robust protection with integrated
overcurrent protection, overvoltage protection, IN to
OUT short detection, and overtemperature protection.
TPS16410 TPS16411, TPS16414, and TPS16415
devices provide ±5% power limiting at 15 W for loads
and it also provide configurable blanking time for
transient overload or overcurrent events. TPS16410,
TPS16411, TPS16414, and TPS16415 can be used
in 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, TPS16413,
TPS16416, and TPS16417 devices provide ±6%
current limiting at 1 A for loads and also provide
output slew rate control with dVdT pin to charge large
capacitive loads at power up.
TPS1641x features IN to OUT short detection and
indicate IN to OUT short on the FLT pin. The FLT pin
either provides to MCU as digital input or to drive an
external PFET.
The devices are characterized for operation over a
junction temperature range of –40°C to +125°C.
