Description

Product Overview

The TPS65217BRSLR is a highly integrated single-chip power management IC (PMIC) from Texas Instruments, specifically designed to power TI Sitara™ AM335x ARM® Cortex®-A8 processors and similar embedded systems. The device integrates three high-efficiency step-down DC/DC converters, four low-dropout (LDO) regulators, a linear battery charger with power path management, and a white LED boost driver, providing a complete power solution for battery-powered and 5 V line-powered applications.

Packaged in a 48-pin VQFN (RSL) package measuring 6 mm × 6 mm with 0.4 mm pitch, the TPS65217B operates from 2.75 V to 5.8 V input and supports dual input sources (USB and AC adapter) with automatic power path management. The three 2.25 MHz synchronous buck converters deliver up to 1.2 A each and provide the core, memory, and I/O voltages for the processor system.

The device features password-protected I²C control (address 0x24), configurable power-up sequencing, power-good monitoring, push-button monitor, wakeup functionality, and an integrated analog multiplexer for system voltage and temperature monitoring. With an operating temperature range of –40°C to +105°C, the TPS65217BRSLR is suitable for industrial and portable applications requiring a compact, cost-effective PMIC solution.

The TPS65217BRSLR is a highly integrated power management IC from Texas Instruments, optimized for TI Sitara AM335x ARM Cortex-A8 processor-based systems. This single-chip PMIC integrates all the power rails required for a typical embedded system: three step-down DC/DC converters for core, memory, and I/O voltages, four LDO regulators for low-power peripherals, a linear battery charger with power path management, and a white LED backlight driver.

Designed for both battery-powered and line-powered applications, the TPS65217B accepts input from USB ports, 5V AC adapters, or single-cell Li-ion/Li-polymer batteries. The integrated power path management automatically selects the appropriate power source and manages the transition between sources without interruption to the system supply.

The three 2.25 MHz synchronous buck converters (DCDC1, DCDC2, DCDC3) provide high-efficiency step-down conversion with dynamic voltage positioning support, allowing software-controlled voltage scaling for power optimization. Each converter supports up to 1.2 A output current with integrated power MOSFETs, minimizing external component count.

The I2C interface with two-level password protection enables secure configuration of all power rails and features. The device includes comprehensive system monitoring: a primary PGOOD signal, LDO power-good output, undervoltage lockout, thermal shutdown, and an 8-channel analog multiplexer for monitoring system voltages and NTC thermistors.

Available in a compact 48-pin VQFN package (6mm x 6mm), the TPS65217BRSLR operates over the full industrial temperature range of -40°C to +105°C, making it suitable for harsh industrial environments.

The TPS65217B PMIC is organized into several major functional blocks:

1. Power Path Management: The power path module manages power flow from three potential sources (AC adapter, USB port, and battery). It automatically selects the highest priority available source and ensures smooth transition between sources. The AC input has the highest priority, followed by USB, then battery. Dynamic Power Path Management (DPPM) prevents system collapse when input current is limited by reducing charging current to maintain system voltage.

2. Battery Charger: A linear charger supports single-cell Li-ion and Li-polymer batteries. Charging phases include precharge (for deeply discharged batteries), constant current fast charge (up to 900mA), and constant voltage float charge. NTC thermistor monitoring ensures safe charging within temperature limits. The charger includes safety timers and thermal regulation.

3. DC/DC Converters: Three synchronous step-down converters (DCDC1, DCDC2, DCDC3) operate at 2.25 MHz using current-mode control. Each converter features soft-start, power-save mode for light load efficiency, short-circuit protection, and 100% duty-cycle low-dropout operation. Output voltages are I2C programmable.

4. LDO Regulators: LDO1 and LDO2 are 200mA standby LDOs that remain active in sleep mode. LS1/LDO3 and LS2/LDO4 can be configured either as load switches or as 200mA LDO regulators, providing flexibility for peripheral power management.

5. WLED Driver: A boost converter with two current sinks drives up to 10 LEDs per string at 25 mA for display backlighting. PWM dimming is supported via I2C control.

6. Control and Monitoring: The I2C interface provides access to all configuration and status registers. A two-level password scheme prevents accidental modification of critical settings. The PGOOD output indicates when all rails are within regulation, and the RESET output provides a power-on reset signal.
