I/O DESCRIPTION PWR_VIN 1 O Power for system output from Vin VIN 2 I Battery supply PWR_VMAX 3 O Switch Controlled supply connected to VMAX. Decouple with a ceramic capacitor VMAX 4 O This pin shows the maximum of VBAT or VBB. Decouple with a 1µF ceramic capacitor LDO_IN 5 I LDO input. Decouple this pin with a 2.2µF ceramic capacitor LDO_OUT 6 O LDO output. Decouple this pin with a 2µF ceramic capacitor PWR_LDO1 7 O Switch Controlled supply connected to LDO output. Decouple with a ceramic capacitor. PWR_LDO2 8 O Switch Controlled supply connected to LDO output. Decouple with a ceramic capacitor. AGND 9 Analog ground connection. Connect to PGND and power Pad. VMICRO 10 O Microcontroller supply CE 11 When low the PMIC is in deep sleep and BIAS supply to the micro is enabled. The Interrupt output is I disabled with a pull down termination. When high, the I2C/SPI is active; the internal switches can be operated, along with the interrupt logic, and Boost/Buck. PWR_BB2 12 O Switch Controlled supply connected to BB output. Decouple with a 1µF ceramic capacitor. BB_EN 13 I Buck-Boost converter enable pin PWR_BB1 14 O Switch Controlled supply connected to BB output. Decouple with a 1µF ceramic capacitor. BB_OUT 15 O Buck-Boost converter output BB_LX2 16 O Buck-boost Boost converter switching node PGND 17 Power ground connection. Connect to AGND and power pad. BB_LX1 18 O Buck-boost Boost converter switching node BB_VIN 19 I Input pin to Buck-Boost converter INT 20 O Push-pull output, asserted when low MISO 21 O Serial Data Transmit interface (Master Input Slave Output) CS 22 I SPI bus Chip Select (active high) when SPI enabled SCL/ SCK 23 I Serial Data Clock (SPI and I2C) MOSI/SDA 24 I Serial Data Receive interface (Master Output Slave Input) for SPI and I2C Copyright © 2013, Texas Instruments Incorporated Submit Documentation Feedback 7 Product Folder Links: TPS65290 |
