TPS2412/13 Evaluation Module, HPA227
This user guide is to facilitate operation of the TPS2412/13 Evaluation Module, HPA227. It is used by an
engineer or technician and supplements the TPS2412/13 datasheet, HPA227 schematics, and HPA227
circuit board labeling.

The TPS2412 controls an N-channel MOSFET to operate in circuit as an ideal diode. The MOSFET
source and drain voltages are monitored by TPS2412 pins A and C. The TPS2412 drives the MOSFET
gate high if V
source and drain voltages are monitored by TPS2412 pins A and C. The TPS2412 drives the MOSFET
gate high if V
AC
exceeds 10 mV, and turns the MOSFET off if V

falls below a threshold that is both
programmable and dependent on the choice of TPS2412 or TPS2413.

TPS2413 is similar to TPS2412 but has a resistor programmable MOSFET turn off point. The TPS2413
can even be set to slightly negative allowing some back current.

shows the conventional wire-OR of power supplies with diodes. Each diode D1 and D2 is
replaced by a TPS2412 and MOSFET eliminating the voltage and power loss in the diode.
The evaluation module is set up to wire-OR two power supplies for redundant power to a load using two
TPS2410s and MOSFETs. This document contains setup and user information about this evaluation
module to assist with the operation of TPS2412.
