OVERVIEW
A block diagram of the DS56 is shown in Figure 1. The
DS56 consists of three major components:
1. Precision bandgap voltage reference
2. Temperature sensor
3. Thermostat comparators
The DS56 incorporates an internal temperature sensor
with a typical transfer function of (in mV with T
expressed in
°
C):
V
TEMP
(T) = 6.2T+ 395
The voltage associated with this transfer function is out-
put on the V
TEMP
pin, which has a typical output imped-
ance of 1.5k
.
The DS56 has two independent temperature compara-
tors, each with its own input (or trip point) and output.
The comparison voltage (the V
TEMP
transfer function) is
the same for both comparators. Additionally, the hyster-
esis for both comparators is typically 5
°
C (31.0 mV).
The DS56 bandgap voltage reference is available on pin
1 to allow for a designer to set the trip point(s) by resis-
tively dividing the reference voltage. One possible sce-
nario is illustrated in Figure 1. For optimum perfor-
mance, the VREF pin should be connected to a 50
μ
A
load.
The comparator outputs are taken off–chip via open–
drain FETs, thus requiring external pull–ups. The ther-
mostat transfer function is illustrated in Figure 2.
The supply range of the DS56 is 2.7V to 5.5V, allowing
for applications ranging from industrial control to bat-
tery–powered portable equipment.
