Using the TPS2410EVM User's Guide Literature Number: SLVU181A October 2006 – Revised February 2012
User's Guide SLVU181A – October 2006 – Revised February 2012 TPS2410 EVM (HPA204) This user's guide is to facilitate operation of the TPS2410 and TPS2411 evaluation module. It is used by an engineer or technician and supplements the TPS2410/11 data sheet, schematics, and circuit board labeling. 1 Introduction The TPS2410 controls an N-channel MOSFET to operate in circuit as an ideal diode. The MOSFET source and drain voltages are monitored by TPS2410 pins A and C.
Introduction www.ti.com Reference Figure 2, a block diagram of the TPS2410EVM and TPS2411EVM. • The 5-V supply is used to power status LEDs. It is jumper selected to power VDD on the TPS2410s and the glitch circuit if the control voltage is less than 3.0 V. • The status outputs turn on LEDs to give a visual condition of the system Fault, power good and gate status are displayed. • The Glitch maker, discussed in the Test Methods Section applies a 1-Ω load to the input supply for 100 μs.
MOSFET Configurations 2 www.ti.com MOSFET Configurations The TPS2410 EVM is supplied with IRL3713 MOSFETS. These MOSFETs can be replaced with user selected parts if desired as there are alternative MOSFET footprints that accept N-channel parts in D2PACK, DPACK, and SOIC packages. The schematic is shown in Section 4. The MOSFETs are configured to operate as singles with only Q6 and Q13 populated as supplied.
LED Indicators www.ti.com 3.4 Jumper Description Jumpers J1, J2, J13, J14 VDD can be powered by the input power supply pin A, Jump J2-2, 3 and J14-2, 3. When it is powered by the load, pin C, jump J2-1, 2 and J14-1, 2. If A and C are less than 3 V, connect the 5 V to VDD, jumper J1-1 to J2 -2 and J13-1 to J14-2. J3, J15 Jumpers J3 and J15 connect a pot to the RSET pin when testing the TPS2411. These jumpers are normally left open when testing the TPS2410.
LED Indicators 3.6 www.ti.com Power Supply Connection Connect the power supplies and load to the TPS2410 test card as shown in Table 3. Loading less than 30 A is safe for IRl3713S. The load can be a test load or the actual system load. Table 3. Power Supply Connection 3.
LED Indicators www.ti.com 3.9 RSET RSET is usually used in TPS2411 and sometimes in the TPS2410 to program the MOSFET turn-off point. The RSET calculation from the data sheet is: æ ö -470.02 RRSET = ç ÷ è VOFF - 0.00314 ø (1) Calculate the RSET resistor. For the PS1 channel, remove jumper J3 and connect an ohm-meter from J3-2 to GND. Adjust pot R8 for the calculated resistance value. Install the jumper J3-1, 2. Repeat for the PS2 channel RSET Pot R26 and jumper J15.
