company blog about Minjiada Electronics Supplies AS8510-ASSM: High Performance Battery Sensing Data Acquisition IC

Shenzhen Mingjiada Electronics Co., Ltd. as a global leading electronic components supplier, has a long-term stable supply of AS8510-ASSM - a high-precision battery sensing and data acquisition IC. AS8510-ASSM is packaged in a SSOP-20 package and is designed for Electric Vehicle (EV), Energy Storage and Industrial Battery Management applications. The AS8510-ASSM is designed for electric vehicle (EV), energy storage system, and industrial battery management applications, providing ultra-high accuracy current, voltage, and temperature measurement capabilities.

The AS8510-ASSM's core strengths of zero temperature drift, low noise, and simultaneous dual-channel ADC sampling make it ideal for battery management systems (BMSs). The AS8510-ASSM is AEC-Q100 automotive grade certified and operates reliably in harsh environments ranging from -40°C to 125°C, ensuring accurate power estimation and safe battery management in EVs36. management.

AS8510-ASSM Core Features

• Dual 16-bit sigma-delta ADCs:
• The AS8510-ASSM is equipped with two independent high-precision ADCs that measure current (mA to kA range) and voltage simultaneously with an error of less than 0.5%.
• The AS8510-ASSM supports a programmable gain amplifier (PGA) that can handle small signals of ±160mV or large signal inputs of 0-1V.
• Zero temperature drift with ultra-low noise:
• AS8510-ASSM adopts a unique auto-zeroing technology with temperature drift <1 LSB and noise <1 LSB @1kHz to ensure long-term stability.
• Flexible Measurement Modes:
• The AS8510-ASSM supports differential/single-ended input configurations to measure current, voltage and temperature (internal/external sensors).
• The AS8510-ASSM has a built-in 4MHz RC oscillator and supports adjustable sampling rates from 1Hz to 8kHz.
• Ultra-low power design:
• Only 40μA current consumption in standby mode, suitable for battery-powered devices.
• Vehicle-grade reliability:
• The AS8510-ASSM is AEC-Q100 compliant and ISO 26262 functional safety certified for EV BMS.
