STEVAL-IFP032V1 STMicroelectronics

S T E VA L - I F P 0 3 2 V 1 Eight-channel high-side driver based on the VNI8200XP-32 Data brief Description The STEVAL-IFP032V1 evaluation board, based on the VNI8200XP-32 high-side driver, is intended for device testing in terms of power management and digital interface. In adherence with industrial standards, the boards isolated interface between the IPS and host controller are implemented using high-speed opto-couplers for IPS driving, and low-speed opto-couplers to receive device status information. Connection is achieved through a 30-pin connector. A GUI interface provides a user-friendly way to test VNI8200XP-32 device functionality, after Features connecting the STEVAL-IFP032V1 evaluation board to a PC via a communication board (part Operating voltage: from 10.5 to 33 V number STEVAL-PCC009V2). Operating current: 1.2 A for each channel Reverse polarity protection Thermal performance is improved thanks to a High-speed opto-isolation for SPI and four-layer design with copper regions distributed parallel communication across all the layers for more effective heat Low-speed opto-isolation for device fault dissipation. The STEVAL-IFP032V1 evaluation signaling board meets EFT standard requirements IEC Step-down converter for 3.3 V or 5 V 61000-4- 2, IEC 61000-4-4, IEC 61000-4-5. Digital supply voltage LED matrix for channel status signaling Microcontroller interface Designed to meet EMC standard requirements: IEC 61000-4-2, IEC 61000-4- 4, IEC 61000-4-5 RoHS compliant February 2016 DocID028944 Rev 1 1/5 www.st.com For further information contact your local STMicroelectronics sales office Schematic diagram STEVAL-IFP032V1 1 Schematic diagram Figure 1: STEVAL-IFP032V1 power section SE L2 SE L1 WD EN WD OUT EN GSPG290 1161205SG 2/5 DocID028944 Rev 1 TP1 TPTH-ANELLO-1MM Ext Vreg D1 CN1 Vreg 1 2 1 2 + 1 STPS1L60 2 TP7 CN2 TPTH-ANELLO-1MM - VCC JP3 JP4 JP5 JP2 Vr e g EXT W D Vr e g Vr e g JP6 2 2 2 2 C8 C9 m m C7 C C m C + m C C10 OPT OUT EN OPT OUT EN TP6 OPT WD EN OPT WD EN 1 OPT SEL1 OPT SEL1 D2 EARTH 2 1 OPT WD TPTH-ANELLO-1MM OPT WD STPSH100A GND Board C11 100pF/10V C12 100pF/10V C13 100pF/10V R56 8k JP11 2 1 C14 100pF/10V GND DISC C15 C16 100pF/10V 1uF/50V l ow ESR MLCC U7 R30 10k R31 270R 1 36 SEL2 NC 35 R32 10k R33 270R 2 35 SEL1/IN1 NC 36 R34 10k R35 270R CN3 3 34 WD EN/IN2 OUT1 OUT1 R36 10k R37 270R 1 4 33 2 OUT EN/IN3 OUT2 R38 10k R39 270R 3 5 32 4 WD/IN4 OUT3 5 R40 100R OPT SDI 6 31 OPT SDI SDI/IN5 OUT4 6 R41 100R 7 OPT CLK 7 30 OPT CLK CLK/IN6 OUT5 8 R42 100R OPT SS 8 29 OUT8 OPT SS SS/IN7 OUT6 TAB=Vcc R43 100R CON8 OPT SDO 9 28 OPT SDO SDO/IN8 OUT7 Vreg 10 27 C17 VREG OUT8 3.3pF/10V 11 26 COL0 NC 26 C20 C21 22nF/50V C22 12 25 COL1 BOOT 4.7pF/10V L1 15 24 Vreg ROW0 PHASE C29 100uH/0.7R Is>700mA 4.7pF/10V 16 22 ROW1 FB TP2 TP3 TP4 TP5 R44 R45 C31 17 C30 ROW2 JP12 4.7pF/10V 10k 1% 1k47 1% 18 21 3V3 ROW3 TWARN GND Board 14 20 PHASE VREF FAULT C32 10nF/10V 13 19 DC/ DC ON DCVDD PG D3 DC/DC R50 2 JP8 2 1 R57 VNI8200 JP7 STPS1L60A FB 33k 5V 2k37 1% DC/ DC OFF C33 C34 FB TWARN R51 115R FAULT R52 115R PGOOD LD2 CH2 2 1 LEDC-0603 2 LD4 1 CH4 LEDC-0603 2 1 CH6 LD6 LEDC-0603 LD8 CH8 2 1 LEDC-0603 2 LD1 1 CH1 LEDC-0603 LD3 CH3 2 1 R53 R54 R55 LEDC-0603 470R 470R 470R 2 1 CH5 LD5 LEDC-0603 LD7 CH7 2 1 Vreg LEDC-0603 TPTH-ANELLO-1MM 1 SDI 1 CL K TPTH-ANELLO-1MM 1 TPTH-ANELLO-1MM SS 1 SDO TPTH-ANELLO-1MM 3 1 R46 10k 10k R47 10k R48 10k R49 3 1 1 3 1 3 1 Vreg 100nF/10V 1 2 10nF/10V 10nF/10V 23 37 GND EP 1 PGOOD 2 1 LD11 LEDC-0603 FAULT 2 1 LD10 LEDC-0603 TWARN2 1 LD9 LEDC-0603 PHASE 3 1 2 1 l ow ESR< 10mohm MLCC 100uF/50V 4.7uF/10V 50ZL100MEFC8X11. 5 2 1 C35 100pF/50V 1uF/50V 22nF/50V C23 C24 22nF/50V TRS1 C25 22nF/50V TRISIL-BIDIR-SMC C26 22nF/50V 4.7nF Y1 / 4kV 22nF/50V C27 C18 22nF/50V C28 22nF/50V 4.7nF Y1 / 4kV C19 22nF/50V
