DESCRIPTION

This product is the HT45F8560 MCU adaptor board for Holtek BMS Workshop. The MCU on the board can be programmed with e-Link or e-WriterPro.

The HT45F85x0 series is Li-ion battery protection Flash MCU with high accuracy LDO (±1%) and a voltage detection circuit which can detect each Li-ion battery voltage with an accuracy of ±0.5%. The series is suitable for 3 to 8 cell Li-ion battery products, such as power tools, cordless hair dryers, cordless vacuum cleaners and so on.

The HT45F85x0 MCU adaptor board is used with the HT45F85x0 MCU development board. There are three types of MCU adaptor board :

The BMS Workshop MCU adaptor boards use two types of MCU, the HT45F8550 and the HT45F8560. The differences between these two MCU are memory size, I/O, ADC and the amounts of timer. Furthermore, the HT45F8560 has one more SPIA interface than the HT45F8550.

NOTE

Please note the direction when the MCU development board connects with the MCU adaptor board. If the battery’s high voltage (higher than 5V) is connected to the non-high voltage pin, the MCU will be damaged.

FEATURES

Operating voltage：1.8V～5.5V
Integrated high accuracy LDO (±1%)
Divided ratio accuracy : ±0.5%
Include a multi-channel 12-bit A/D converter, a comparator, a high accuracy voltage regulator and Li-ion rechargeable battery protection functions

CONNECTING INTRODUCTION

Before the MCU adaptor board connect to the MCU development board, please make sure that the lower right pin numbers of the MCU adaptor board are 1 and 48, these two numbers also can be found on the lower right of the MCU development board. (As the following picture for reference)
The C3 (2.2nF) has been soldered on the MCU development board. Therefore, the C3 (2.2nF) can not be soldered on MCU adaptor board again, otherwise the voltage detection will be not correct due to capacitors in parallel connection.
