UPD168104

DATA SHEET MOS INTEGRATED CIRCUIT μ PD168104 6-CHANNEL OPERATIONAL AMPLIFIER, IRIS DRIVER, AND 4-CHANNEL H-BRIDGE DRIVER DESCRIPTION The μ PD168104 is the motor driver IC with IRIS control circuit, operational amplifier and 4-ch H-bridge output. Smooth operation is possible for IRIS control with linear method. The package is 56-pin thin type QFN and then it helps reduce the mounting area and height. The μ PD168104 is suitable for the lens drive of a camcorder, DSC, etc. FEATURES 5-ch H-bridge circuits employing power MOSFET Stepping motors driver : 4 circuits, IRIS driver : 1 circuit. Low-voltage driving LVDD = 2.7 to 3.6 V, AVDD = 4.5 to 5.5 V, VM = VSHUTTER = VIRIS = 2.7 to 5.5 V Output on-state resistance: 2.0 Ω TYP., 3.0 Ω MAX. (4-ch H-bridge block, sum of top and bottom stage, VM = 5 V) PWM output (ch1 to ch4) Output current DC current: ±0.3 A/ch (when each channel is used independently) Peak current: ±0.7 A/ch (when each channel is used independently) 6-ch general-purpose operational amplifier Input offset voltage: ±5 mV Input voltage range: 0 to AVDD − 1.5 V Output voltage range: 0.2 to AVDD − 0.2 V 1-ch 1/2AVDD output amplifier IRIS driver block supporting linear driving Pre-driver amplifier of the IRIS driver block Undervoltage lockout circuit Output circuit and amplifier stop at LVDD = 1.7 V TYP. or less. Overheat protection circuit Operates at 150°C or more and shuts down the output circuit. Mounted on 56-pin plastic WQFN (8 x 8) APPLICAT...
