# L9396 (Component) ## Description Automotive multiple power supply IC designed as a system basis chip for automotive electronics, integrating a switched-mode pre-regulator, three linear regulators, and a configurable 0.8 V to 5 V microcontroller core regulator with up to 1 A buck or 750 mA linear output. It operates from a 4.5 V to 19 V supply with boost (6 V to 19 V without boost), supports a 16-bit SPI interface, includes a 4-channel wheel speed sensor interface, 10-bit ADC, configurable watchdogs, high-side pre-drivers, and is housed in a 64-pin TQFP exposed-pad package. #AutomotiveIC #PowerManagementIC #SystemBasisChip #PMIC #SPI #WheelSpeedSensor #ADC #Watchdog #TQFP64 #STMicroelectronics ## Component Details - **Owner:** silicon-yard - **Created:** 8/6/2026 - **Last Updated:** 8/6/2026 - **Visibility:** Public - **Datasheet URL:** https://www.st.com/content/ccc/resource/sales_and_marketing/promotional_material/selection_guide/group0/00/1a/3c/20/ef/24/42/62/Automotive%20powertrain%20and%20safety%20ICs/files/SGPWTRAIN.pdf/jcr:content/translations/en.SGPWTRAIN.pdf - **Package or Case Code:** 64-TQFP-EP (10x10) - **Manufacturer Part Number:** L9396 - **License:** https://creativecommons.org/licenses/by/4.0/ - **Symbol Style:** parametric-v1 - **Manufacturer Name:** STMicroelectronics - **Part Type:** Integrated Circuit - **Part Type:** Integrated Circuits - **Sub-Type:** Logic - **Manufacturer:** STMicroelectronics - **MPN:** L9396 - **Package / Case Code:** 64-TQFP - **Pin Count:** 65 - **Logic Function:** AND ## Pins | Pin | Name | Type | |-----|------|------| | 38 | VCC | | | 43 | VBST | | | 23 | VB_SW | | | 24 | VB | | | 44 | CP | | | 29 | VBM | | | 40 | VPREREG | | | 39 | VCC5 | | | 25 | VDBATT | | | 50 | FSN | | | 27 | VDS | | | 64 | FAULT | | | 26 | VDG | | | 41 | VCCSEL | | | 1 | AI4 | | | 28 | WDTDIS | | | 4 | AI1 | | | 3 | AI2 | | | 30 | IGN | | | 2 | AI3 | | | 5 | AI0 | | | 42 | BCKSW | | | 48 | VC1 | | | 51 | BSTSW | | | 47 | VC2 | | | 46 | VC3 | | | 45 | VC4 | | | 16 | PDI | | | 17 | PRI | | | 22 | PDBATT | | | 21 | PDS | | | 20 | PDG | | | 19 | PRS | | | 18 | PRG | | | 10 | RSUL2 | | | 9 | RSUH1 | | | 63 | WSO3 | | | 61 | WSO1 | | | 6 | RSUL0 | | | 8 | RSUL1 | | | 13 | RSUH3 | | | 60 | WSO0 | | | 7 | RSUH0 | | | 12 | RSUL3 | | | 62 | WSO2 | | | 11 | RSUH2 | | | 53 | NU | | | 15 | GPOD0 | | | 33 | SCORE | | | 35 | CBS | | | 36 | I_CORE_SL | | | 32 | VCORE | | | 34 | GCORE | | | 37 | I_CORE_SH | | | 31 | VCOREFDBK | | | 59 | CS | | | 57 | CLK | | | 58 | PRN | | | 55 | SDO | | | 56 | SDI | | | 49 | RESET | | | 14 | GNDA | | | 65 | EP | | | 52 | GNDBST | | | 54 | GNDD | | --- *Generated from [https://www.flux.ai/silicon-yard/l9396](https://www.flux.ai/silicon-yard/l9396)*
