MEZS7-1S-4SPDPOWERBANK

MEZS7-1S-4SPDPowerBank Bidirectional PD Power Bank Solution with Fully Integrated Buck-Boost Charger for 1-Cell to 4-Cell in Series Battery Packs DESCRIPTION The MEZS7-1S-4SPDPowerBank is a solution module for PD applications with the MP2651 and CCG3PA, supporting PD3.0 and BC1.2 protocols. The MP2651 is a buck-boost charger designed for battery packs with 1 cell to 4 cells in series. The device supplies a wide 3V to 21V voltage range at the IN pin in source mode. It is compliant with USB PD specifications. The CCG3PA is a Cypress PD controller that handles the PD protocol. The MEZS7-1S-4SPDPowerBank contains a DRP USB Type-C port. When an adapter is inserted, the port acts as a UFP to charge the battery with a maximum 5A charge current. When a load is inserted, the port acts as a DFP to power the USB from the battery. PERFORMANCE SUMMARY (1) Specifications are at TA = 25°C, unless otherwise noted.

Its layout accommodates most commonly used capacitors. The charge current is preset to 5A, and the charge-full voltage is preset to 8.4V for a Li-ion battery with 2 cells in series. In reverse source mode, the output is preset to 5V/3A. All of the charging/discharging parameters are set by the CCG3PA. The user can also download their own codes to the CCG3PA through the board’s configuration header. 1. Connect the battery terminal to: a. Positive (+): VBATT b. Negative (-): GND 2. If using a battery simulator, preset the battery voltage between 0V and 8.4V, then turn it off. Connect the battery simulator’s ports to: a. Positive (+): VBATT b. Negative (-): GND 3. Ensure that the battery voltage is present (if using a battery simulator, keep the simulator on). 4. For charge mode testing, connect the USB Type-C port to an adapter with a USB Type-C to Type-C cable or USB Type-A to USB Type-C cable. Charge mode should start automatically, and the charge current is adjusted according to the PD protocol communication result between the adapter and board. 5. For source mode testing, connect the devices to a USB Type-C port with a USB Type-C to Type-C cable, USB Type-C to Micro-B cable, or a USB Type-C to lighting cable. Source mode should start automatically and provide the required voltage to the devices. Figure 1 shows the measurement equipment set-up.
