V048x060y040A
TEMPERATURE MONITOR : TM
• The TM pin monitors the internal temperature of the VTM controller IC
• The TM pin has a room temperature setpoint of 3 V
within an accuracy of ±5°C.
and approximate gain of 10 mV/°C.
• Can be used as a "Power Good" flag to verify that the VTM is operating. • Output drives Temperature Shutdown comparator

Notes:
– Timing and voltage is not to scale
– Error pulse width is load dependent
