E2 SW_B1 O P Buck Switcher Regulator 1 - Power Switching node, connect to inductor D1 FB_B1 I A Buck Switcher Regulator 1 - Voltage output feedback for Buck Regulator 1 D3/E3 GND_B1 G P Buck Switcher Regulator 1 - Power ground for Buck Regulator A1 VIN_B2 I P Buck Switcher Regulator 2 - Power supply voltage input for power stage PFET. A2 SW_B2 O P Buck Switcher Regulator 2 - Power Switching node, connect to inductor B1 FB_B2 I A Buck Switcher Regulator 2 - Voltage output feedback for Buck Regulator 2 A3/B3 GND_B2 G P Buck Switcher Regulator 2 - Power ground for Buck Regulator E4 VIN I P Power supply Input Voltage, must be present for device to work C4 LDO_VIN I P LDO Regulator - LDO input voltage can be only come from bump D4/E4 -VIN or if not used has to be connected to C3-GND B4 LDO_OUT O P LDO Regulator - LDO output voltage can only be connected to bump A4 to provide VIN_IO or is not used A4 VIN_IO P A Supply Voltage for Digital Interface can be supplied from any external supply or bump B4 - LDO_OUT A5 SPI_CS I D SPI Interface – chip select C5 SPI_DI I D SPI Interface – serial data input B5 SPI_DO O D SPI Interface – serial data output D5 SPI_CLK I D SPI Interface – serial clock input E5 RESET I D Digital Input Control Signal to abort SPI transactions and resets the PMIC to default Voltages D4 VCOMP I A Analog Input for Comparator. Can only be connected to monitor E4-VIN C1 IRQ O D Digital Output of Comparator to signal Interrupt condition from Comparator input VIN C3 GND G G Ground. Connect to system Ground. C2 GND G G Ground. Connect to system Ground. B2 NC Do not connect D2 NC Do not connect Absolute Maximum Ratings (1) (2) VIN, VCOMP −0.3V to +6.0V VIN_IO, VIN_B1, VIN_B2, SPI_CS, SPI_DI, SPI_CLK, SPI_DO, RESET, IRQ −0.3V to VVIN Junction Temperature (TJ-MAX) 150°C Storage Temperature −65°C to 150°C ESD Rating Human Body Model (HBM) 2.0kV (1) Absolute Maximum Ratings are limits beyond which damage to the device may occur. Operating Ratings are conditions under which operation of the device is ensured. Operating Ratings do not imply ensured performance limits. For ensured performance limits and associated test conditions, see the General Electrical Characteristics. (2) If Military/Aerospace specified devices are required, please contact the TI Sales Office/Distributors for availability and specifications. 4 Submit Documentation Feedback Copyright © 2012–2013, Texas Instruments Incorporated Product Folder Links: LM10502 |
