Top View Table 1. Typical Jumper Connections JP1 JP2 JP3 FS2 FS1 FS0 OFF OFF ON ON ON ON Power Supply • Ensure that all external power sources are set to OFF. • Connect a 4.5-V to 26-V power supply to (PVCC) and (GND), taking care to observe proper polarity. Inputs and Outputs • Connect a dc control voltage to (IN+) ranging from 0.5-V to 5.5-V. Alternately, the terminal (IN+) can be held to a fixed voltage with a resistor voltage divider, as shown in the schematic. A dc control voltage applied to IN- of the same magnitude provides 0-V output from OUT+ to OUT–. • Connect a load across (OUT+) and (OUT–). The polarity of the connection depends on the operation of the dc control voltage. As the voltage at IN+ becomes greater than the voltage at IN–, the voltage at OUT+ increases, causing current to flow from OUT+ to OUT–. Similarly, as the voltage at IN+ decreases lower than IN–, the voltage at OUT– increases, causing current to flow from OUT– to OUT+. Evaluation Module Jumpers • Jumper JP1 (HI-Z) should be OFF for normal operation. When JP1 is ON, the output of DRV595 is disabled. This jumper is for fast disabling or enabling of outputs. • Jumper JP2 (MODSEL) gives the option of running in either 1SPW modulation or BD modulation. When JP1 is ON, the DRV595 operates on 1SPW mode. The 1SPW mode alters the normal modulation scheme in order to achieve higher efficiency with a slight penalty in ripple current and more attenuation required in the output filter selection. When JP1 is OFF, the DRV595 operates in BD mode. In BD mode, the device allows for smaller ripple current through the TEC load. 4 DRV595 EVM SLAU479 – December 2012 Submit Documentation Feedback Copyright © 2012, Texas Instruments Incorporated Operating Instructions List www.ti.com • • Jumper JP3 (SDZ = FAULTZ) should be ON for normal operation. When Jumper JP3 is ON, the FAULTZ signal is connected to SDZ. When Jumper JP3 if OFF, the SDZ is disconnected from FAULTZ, so the fault signal can’t affect to shutdown. The FS0-FS2 is for oscillator frequency selection. Table 2.
