Internal structure

Schematic diagram

JC-K2 series controller performance requirements:
Rated voltage VCES: consider the full battery voltage, parasitic inductance, di/dt and other effects, generally more than two times the voltage of the battery
Rated current IC: consider the peak power of the motor
Working frequency: VCEsat is required to be positive temperature coefficient, as low as possible, turn off the good soft
Safe working area: short circuit resistance, high RBSOA, better have certain avalanche resistance
Tjmax is more than or equal to 150 DEG C
The module has low thermal resistance and large heat capacity
EMI
Reliability requirements for JC-K2 series controllers:
Test items, test conditions and requirements:
Temperature cycling (TC) -40 to 125 DEG C, cycles = 1000
Thermal shock test (TS) -40 to 125 DEG C, cycles = 100
Mechanical vibration (MV) = 10g, 2hrs per axis (x, y, z)
Mechanical shock (MS) 3 times more than 100g, each direction (+ X, + y, + Z)
High temperature storage (HTS) Ta=150 C = 1000hrs
Low temperature storage (LTS) Ta=-40 C = 1000hrs
