Output Pins
Pin # Pin Name Function
1 TEMPOUT IC chip temperature (MDC901 internal sensor). Measure voltage and
calculate temperature according to Section “Temperature Measurement”
2 NTC_In Board temperature. Measure resistance between NTC_In and NTC_Out to
calculate temperature according to Section “Temperature Measurement”
3 NTC_Out Board temperature at NTC, placed just below MDC901. See NTC_In.
4 UVLS Digital output, undervoltage on the LS supplies (both regulated as
preregulated supply levels). Will give a low output in case of undervoltage
condition.
5 UVHS Digital output, undervoltage on the HS supplies (both regulated as
preregulated supply levels). Will give a low output in case of undervoltage
condition.
6 PP_Alarm Open-drain output, for detecting push-pull errors in the gate sensing.
Active low.
7 TMGateHS Digital signal, gate feedback of high-side driver
8 TMGateLS Digital signal, gate feedback of low-side driver
9 VDD_LOGIC Digital 5V linear regulator. Can drive limited external resistive loads, but
should not be loaded capacitively.
For more information on the pin functions, refer to the MDC901 datasheet.
Vin, Vbus and Vout
Vin is connected to the low voltage power supply and has an allowable input range of 15-42V. Vbus is
connected to the high power, high voltage power supply and with an intended input range of 0-48V. Vout is
the stepped down, outgoing power, connected to the (electronic) load with a voltage range of 0 to Vbus.
