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)
APPLICATIONS
Lens motor driving for DVC and DSC, etc.

3. FUNCTION OPERATION TABLE
3.1 Reset Function
The internal circuit is shut off and the circuit current is kept to 1 μA MAX. when the RESETB pin is set L (reset
status). In this status, all of the output pins are Hi-Z (High impedance). Set the RESETB pin H for normal usage.
Remark H: High level, L: Low level
