µPD168103A
Stepping Motor Driver
5-channel Operational Amplifier, IRIS Driver, and 4-channel H-bridge Driver
Overview
The µPD168103A is a lens motor driver IC for the DVC and DSC. In addition to ordinary H-bridge output, it has ancillary devices such as an IRIS driver for linear driving and a general-purpose operational amplifier, to assist in the creation of small sets.
Features
- 5-ch H-bridge circuits employing power MOS FET
- Low-voltage driving
LVDD = 2.7 to 3.6 V
AVDD = 4.5 to 5.5 V
VM12 = VM34 = VSHUTTER = VIRIS = 2.7 to 5.5 V - Output on-sate 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) - 3-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 current sink amplifier
Output current: 5 mA - 1-ch 1/2LVDD 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. - 48-pin plastic WQFN (7 x 7 mm)
