Product details
Overview
TPS658600AZQZR from Texas Instruments is an advanced power management unit (PMU) for handheld devices, integrating battery charging, three programmable step-down converters (max 1.2A each), eleven LDOs, an 11-channel ADC, dual RGB LED drivers, and a constant-current WLED driver. It supports dual-input power path, USB current limiting, and I²C-controlled system management in a 6×6 mm BGA package.
For engineers reviewing the TPS658600AZQZR datasheet, TPS658600AZQZR pinout, TPS658600AZQZR application, or TPS658600AZQZR equivalent, key selection considerations include its 120-pin MICROSTAR JUNIOR BGA package, integrated display support (4 PWM outputs + WLED/RGB drivers), thermal foldback protection, programmable charge current up to 1.0A, and host interface with maskable interrupts and ADC triggering.
Technical Context
The TPS658600AZQZR implements a dual-input power path architecture that dynamically manages Li-ion/Li-polymer battery charging from either adapter or USB sources, with over-voltage protection up to 18V and thermal foldback. Its system management includes hardware on/off control, software reset, and power-good monitoring across all regulated outputs.
Display support is implemented via four independent PWM generators (programmable frequency/duty cycle), two RGB LED drivers, and a dedicated constant-current WLED driver rated for 26.5V at 25mA with programmable brightness and current level control.

FAQ
What is the maximum input voltage rating for TPS658600AZQZR?
The TPS658600AZQZR features integrated over-voltage protection rated at a maximum of 18V on its VIN1 and VIN2 inputs. This protects the device and downstream circuitry from transient surges or incorrect adapter connections. The protection operates independently per input rail and does not require external components. TPS658600AZQZR maintains safe operation within this limit while supporting both wall adapter and USB power sources.
Does TPS658600AZQZR support programmable battery charge current?
Yes, TPS658600AZQZR supports fully programmable charge current up to 1.0A via I²C register settings. Charge parameters-including adapter/USB current limits, termination thresholds, and recharge voltage-can be configured in real time. This flexibility allows TPS658600AZQZR to adapt to varying battery chemistries and capacity requirements without hardware changes.
How many regulated power outputs does TPS658600AZQZR provide?
TPS658600AZQZR delivers 14 regulated power outputs: three high-current step-down converters (each capable of up to 1.2A), and eleven low-dropout regulators (LDOs). Among the LDOs, seven are fixed-output (1.25–3.3V), two are factory-configurable, one is always-on, and one is optimized for 1.70–2.475V operation. All outputs are individually controllable and monitorable via I²C.
Can TPS658600AZQZR drive white LED backlights directly?
Yes, TPS658600AZQZR integrates a dedicated constant-current WLED driver with WLED+/WLED− terminals, rated for up to 26.5V forward voltage at 25mA. It supports programmable current level and brightness control via PWM dimming. This eliminates the need for external boost converters or LED driver ICs in display backlight applications using TPS658600AZQZR.
What package type and pin count does TPS658600AZQZR use?
TPS658600AZQZR uses a 6×6 mm, 120-ball MICROSTAR JUNIOR BGA package (ZQZ drawing) with SNAGCU surface finish and JEDEC MSL Level-3 moisture sensitivity rating. The 120-ball layout supports dense routing for high-pin-count power management in space-constrained handheld PCBs, and is compatible with standard reflow profiles for lead-free assembly.
