Temperature Monitor • The TM pin is a standard analog I/O configured as an output from an internal µC. • The TM pin monitors the internal temperature of the controller IC within an accuracy of ±5°C. • µC 250 kHz PWM output internally pulled high to 3.3 V. SIGNAL TYPE STATE ATTRIBUTE SYMBOL CONDITIONS / NOTES MIN TYP MAX UNIT DIGITAL OUTPUT Startup Powertrain active to TM time tTM 100 µs Regular Operation TM Duty Cycle TMPWM 18.18 68.18 % TM Current ITM 4 mA Recommended External filtering TM Capacitance (External) CTM_EXT Recommended External filtering 0.01 µF TM Resistance (External) RTM_EXT Recommended External filtering 1 kΩ Specifications using recommended filter TM Gain ATM 10 mV / °C TM Voltage Reference VTM_AMB 1.27 V TM Voltage Ripple VTM_PP RTM_EXT = 1 K Ohm, CTM_EXT = 0.01 uF, VPRI_DC = 54 V, ISEC_DC = 150 A 28 mV TINTERNAL ≤ 100ºC 40 Enable / Disable Control • The EN pin is a standard analog I/O configured as an input to an internal µC. • It is internally pulled high to 3.3 V. • When held low the BCM internal bias will be disabled and the powertrain will be inactive. • In an array of BCMs, EN pins should be interconnected to synchronize startup and permit startup into full load conditions.
