Applications
PAMC1300BQDWVRQ1 is designed for automotive traction inverters and battery management systems where high-voltage isolation between the power stage and control MCU is mandatory for functional safety. Its ±250 mV input range and 310 kHz bandwidth allow real-time phase-current monitoring across a shunt resistor in three-phase motor drives without additional signal conditioning. The 5000 V reinforced isolation rating and AEC-Q100 qualification make it a direct fit for 400 V and 800 V EV powertrain platforms.

Frequently Asked Questions
What isolation voltage does PAMC1300BQDWVRQ1 provide, and how does that meet automotive EV powertrain safety requirements?
PAMC1300BQDWVRQ1 provides a minimum 5000 V reinforced isolation between its input and output sides. For 400 V and 800 V battery electric vehicle traction systems, IEC 60664-1 requires reinforced insulation rated to at least 2500 V for Class I equipment; this device exceeds that margin with a 5000 V rating, supporting reliable isolation between the high-voltage bus and the 3.3 V MCU domain.
How wide is the signal bandwidth of PAMC1300BQDWVRQ1 and is it fast enough for real-time overcurrent protection in a 20 kHz switching inverter?
PAMC1300BQDWVRQ1 has a -3 dB bandwidth of 310 kHz, which is more than 15 times faster than a 20 kHz inverter switching frequency. This allows the amplifier to accurately reproduce current waveforms through each PWM cycle and respond to fault conditions within microseconds, well within the 50 µs window typical of fast overcurrent protection schemes in automotive motor controllers.
What input voltage range does PAMC1300BQDWVRQ1 accept, and how should the shunt resistor be sized for a 100 A phase current measurement?
PAMC1300BQDWVRQ1 accepts a differential input from -250 mV to +250 mV. For a 100 A peak phase current, a 2.5 mΩ shunt resistor produces a 250 mV full-scale voltage that exactly fills the input range, while dissipating only 25 mW at peak current to minimize thermal impact on measurement accuracy. A 2 mΩ shunt provides additional headroom for 125 A fault currents.
Is PAMC1300BQDWVRQ1 a drop-in replacement for AMC1301 in existing automotive current sense designs?
PAMC1300BQDWVRQ1 is pin-compatible with the AMC1301 and shares the same 8-pin SOIC package and ±250 mV input range. The key distinction is the AEC-Q100 Grade 1 qualification of PAMC1300BQDWVRQ1, which extends the guaranteed operating range to -40°C to +125°C and adds the reliability screening required for automotive OEM bill-of-materials approval. Designers can substitute PAMC1300BQDWVRQ1 in existing AMC1301 footprints without schematic changes.
