PIN I/O DESCRIPTION
NAME NO.
VDD 1 PWR Input power for the gate drive charge pump and internal controls. VDD must be connected to a supply voltage ≥ 3 V.
RSET 2 I Connect a resistor to ground to program the turn-off threshold. Leaving RSET open results in a slightly positive V(A-C) turn-off threshold.
STAT 3 I/O STAT is a multifunction pin. A high output indicates that the MOSFET gate is being driven high. Overdriving STAT low while GATE is high shifts the fast-turnoff threshold negative. STAT has a weak pull-up to VDD.
FLTB 4 O Open drain fault output. Fault is active (low) for any of the following conditions:
  • Insufficient VDD
  • GATE should be high but is not.
  • The MOSFET should be ON but the forward voltage exceeds 0.4 V.
OV 5 I OV is a voltage monitor that contributes to the PG output, and also causes the MOSFET to turn off if it is above the 0.6-V threshold. OV is programmable via an external resistor divider. An OV voltage above 0.6 V indicates a bus voltage that is too high.
UV 6 I UV is a voltage monitor that contributes to the PG output. The UV input has a 0.6 V threshold and is programmable via an external resistor divider. A UV voltage above 0.6V indicates a bus voltage that is above its minimum acceptable voltage. A low UV input does not effect the gate drive.
GND 7 PWR Device ground.
GATE 8 O Connect to the gate of the external MOSFET. Controls the MOSFET to emulate a low forward-voltage diode.
RSVD 9 PWR This pin must be connected to GND.
C 10 I Voltage sense input that connects to the simulated diode cathode. Connect to the MOSFET drain in the typical configuration.
A 11 I Voltage sense input that connects to the simulated diode anode. A also serves as the reference for the charge-pump bias supply on BYP. Connect to the MOSFET source in the typical configuration.
FLTR 12 I A capacitor connected from FLTR to A filters the input to the fast comparator. Filtering allows the TPS2410 to ignore spurious transients on the A and C inputs. This pin may be left open to achieve the fastest response time.
BYP 13 I/O Connect a storage capacitor from BYP to A to filter the gate drive supply voltage.
PG 14 O An open-drain Power Good indicator. PG is open if the UV input is above its threshold, the OV is below its threshold, and the internal UVLO is satisfied.
