NAME TPS2560 TPS2561
4 - I Enable input, logic low turns on channel one
EN1
power switch
EN1 - 4 I Enable input, logic high turns on channel one
power switch
5 - I Enable input, logic low turns on channel two
EN2
power switch
EN2 - 5 I Enable input, logic high turns on channel two
power switch
GND 1 1 Ground connection; connect externally to
PowerPAD
IN 2, 3 2, 3 I Input voltage; connect a 0.1 μF or greater
ceramic capacitor from IN to GND as close to the
IC as possible.
FAULT1 10 10 O Active-low open-drain output, asserted during
overcurrent or overtemperature condition on
channel one.
FAULT2 6 6 O Active-low open-drain output, asserted during
overcurrent or overtemperature condition on
channel two
OUT1 9 9 O Power-switch output for channel one
OUT2 8 8 O Power-switch output for channel two
ILIM 7 7 O External resistor used to set current-limit
threshold; recommended 20 kΩ ≤ R
ILIM
≤ 187 kΩ.
Internally connected to GND; used to heat-sink
PowerPAD
PAD PAD the part to the circuit board traces. Connect
™
PowerPAD to GND pin externally.
