Temperature Sensor ICs
Low Current Thermostat Output
BDJxxx0HFV Series
General Description
BDJxxx0HFV series is a thermostat output temperature
sensor IC with built-in temperature detection element,
constant current circuit, and a high-accuracy reference
voltage source in one chip. Temperature detection can
be realized at ±2.5°C accuracy without the need for a
complicated design. It is best suited for portable
equipment of micro- and low-current, power down
function, and battery drive. It is possible to use it for a
wide range of applications such as heat detection and
temperature monitors because it provides an analog
output in addition to the thermostat power output.
BDJxxx0HFV series has 5 products at 55°C, 60°C,
65°C, 70°C, and 80°C detection temperature.

(Note 2) When mounted on ROHM standard board, derate by 5.36mW/°C for Ta higher than 25°C.
Caution:
Operating the IC over the absolute maximum ratings may damage the IC. The damage can either be a short circuit between pins or an open circuit
between pins and the internal circuitry. Therefore, it is important to consider circuit protection measures, such as adding a fuse, in case the IC is operated over
the absolute maximum ratings.
