SM6610 series CMOS Monolithic Temperature Sensor IC NIPPON PRECISION CIRCUITS INC. OVERVIEW FEATURES ■ High linearity: ± 0.5% typ. (Ta = –20 to 80°C) Operating temperature range: –40 to 100°C (VDD ≥ 2.7V) Maximum output current load: ± 250µA Output reference: VSS Low current consumption: 5.5µA typ. (Ta = 25°C) ■ ■ ■ Low stand-by current: 0.5µA max. Very small plastic package: SC82AB Very small leadless package: VSP-4 Power down function Molybdenum-gate CMOS Process pre lim ina ■ ry SM6610 series is high-accuracy temperature sensor IC in the ultra small package. By using CMOS circuit, it realizes low voltage and low current consumption. The power down function contributes to decrease the current consumption of application set by activating intermittent function easily. ■ ■ ■ ■ ■ PINOUT (Top view) VSP-4 SC82AB VDD 1 4 OUT VSS 2 3 PDN VDD 1 4 OUT VSS 2 3 PDN ORDERING INFORMATION D e vice P ackag e SM6610AH SC82AB SM6610AD VSP-4 SM6610BH SC82AB SM6610BD VSP-4 Output center current [V] (Ta = 25 °C) Temperature coefficient [mV/ °C] Operating voltag e [V] A c c u r a cy [°C] 1.933 – 10.7 4.0 to 6.0 ± 5.0 1.449 – 8.2 2.4 to 6.0 ± 5.0 NIPPON PRECISION CIRCUITS—1 SM6610 series PACKAGE DIMENSIONS (Unit : mm) VSP-4 ina ry 1.30 0.60 ± 0.1 C0.15 0.05 2.0 ± 0.1 1.25 ± 0.1 0.8 SC82AB lim 0.05 0.33 ± 0.05 +0.07 0.93 −0.1 0.02 ± 0.005 0.05 + 0.2 2.0 − 0.1 0.3 + 0.1 0.4 − 0.05 + 0.1 0.3 − 0.05 0.9 ± 0.1 0.15 0 to 0.1 1.3 ± 0.2 0.1 2.1 ± 0.3 0.4 0.3 + 0.1 0.125 − 0.05 0.3 pre + 0.2 1.25 − 0.1 0.3 0.10 M NIPPON PRECISION CIRCUITS—2 SM6610 series BLOCK DIAGRAM ina ry VDD Constant current source − Amplifier OUT + Temperature sensor VSS Number 1 2 3 4 lim PIN DESCRIPTION PDN Name Description VDD Positive pow er supply VSS Ground PDN1 Pow er down control.
