DESCRIPTION
The TSM109 is a monolithic IC that includes two
comparators and a shunt voltage reference. This
device offers space and cost savings in many ap-
plications including power supply management or
data acquisition systems.

1. At output switch point, Vo ≈ 1.4V, Rs = 0 with VCC+ from 5V to 30V, and over the full common-mode range (0V to VCC+ -1.5V).
2. The direction of the input current is out of the IC due to the PNP input stage. This current is essentially constant, independent of the state of the
output, so no loading charge exists on the reference of input lines.
3. The response time specified is for a 100mV input step with 5mV overdrive. For larger overdrive signals, 300ns can be obtained.
