SD59D25AC is a highly integrated protocol and power control chip applied to the multi-in-one solution for travel chargers and mobile power supply,. It integrates 3 USB ports (up to two Type-C ports), and is compatible with fast charging protocols such as PD3.1, PPS, QC4.0+, FCP, SCP, AFC, BC1.2, APPLE2.4, VOOC, and UFCS.
In the mobile power supply mode, the built-in 4-channel dead-time controllable PWM controller enables bidirectional, Buck-Boost switching power supply conversion. It supports high-precision constant voltage and constant current, enabling the charging and discharging management of lithium batteries. With a built-in high-precision ADC, it supports accurate coulombmeter-based power calculation.
In the charger mode, a built-in TL431 is provided, supporting the optocoupler control mode, which can flexibly control the ACDC power supply to achieve constant voltage and constant current output.
It supports the LPS function.
Operating voltage range: 3.3V~40V
Protocols support: PD3.1, PPS, QC4.0+, FCP, SCP, AFC, BC1.2, APPLE2.4, VOOC, UFCS
Supports the independent parsing of the protocols for 2 pairs of CC ports and 3 pairs of DD ports.
The PWM controller with controllable dead zone supports the setting of a PWM switching frequency ranging from 100 to 350kHz.
Supports two-channel voltage and current sampling, and enables independent constant voltage and constant current control in both the power supply mode and the charger mode. It can support a maximum charging and discharging power of 140W.
Supports three-channel load switches control
I2C/UART communication
LED indication and digital tube display
High-precision access detection and removal detection of powered equipment
Support IDEL/STOP low power dissipation mode
Built-in over voltage protection, over current protection
