DESCRIPTION

The TS12011/TS12012 combine a 0.58V reference, a

20µs comparator, and a unity-gain stable op amp in a

single IC. All three devices operate from a single 0.8V

to 2.5V power supply and consume less than 1.6µA

total supply current. Supply current for all three

functions

over

0.8V

to

2.5V

supply

range

is

guaranteed 1.6µA max.

Super-flexible for crafting voltage detectors, timers,

and wake-up circuits, these bundled functions exhibit

low shoot-through currents and graceful power-down

modes. Both the comparator and the op amp feature

rail-to-rail input stages. The latching comparator

exhibits ±7.5mV of internal hysteresis for clean,

chatter-free

output

switching.

When

compared

against similar products, the TS12011/TS12012 offer

a factor-of-20 lower power consumption and at least a

55% reduction in pcb area.

The TS12011’s comparator has a push-pull output

stage with break-before-make switches for low shoot-

through currents. The TS12012’s comparator has an

open-drain output having no parasitic diode to VDD,

for interfacing to wired-OR or mixed-voltage logic.

The TS12011 and the TS12012 are fully specified

over the -40°C to +85°C temperature range and each

is available in a low-profile, 10-pin 2x2mm TDFN

package with an exposed back-side paddle.
