BLOCK DIAGRAM

THEORY OF OPERATION

The TS12011 and TS12012 are multi-purpose CMOS

building blocks intended for creating analog glue

functions around battery-powered uC systems. There

is an op amp for signal conditioning, a comparator for

detection, and a reference to establish detection

threshold levels. It’s possible to build a wide variety of

timers, event detectors, regulators, and voltage

monitors using these flexible uncommitted blocks.

Optimized for low-voltage operation, these devices

draw less than 1.6uA total from a 0.8V to 2.5V

supply. The op amp and comparator blocks typically

(REFOUT will go into dropout, however).

Comparator

The comparator block is designed for high gain and

chatter-free output switching in noisy environments.

The comparator inputs have rail-to-rail VIN range,

and exhibit +/-7.5mV of hysteresis.

The only

difference between the two device types is in the

output stage of the comparator. The TS12011 has a

push-pull output and latches in the high state. The

TS12012 has an open-drain output, latches in the low

state, and can tolerate pull-up voltages higher than

the

supply

(up

to

5.5V

above

VSS/GND).

TS12011 push-pull output driver was designed to

minimize supply-current surges while driving ±100µA

loads with an output swing to within 100mV of the

supply rails. The TS12011 and the TS12012 can sink

0.5mA and 1.4mA of current, respectively. The

TS12011 can source 0.1mA of current.

The non-traditional latch function works to detect and

latch changes in the input state. If the LHDET

control

input is enabled, the output will latch high (low for the

TS12012) whenever the differential input voltage is

high enough to force a change in that direction. If the

differential voltage is in the wrong direction to force a
