- Input/Output Voltage: -0.3V to DVDD + 0.3V
- Storage Temperature: -55°C to 125°C
- Operating Temperature: -20°C to 85°C
️· Recommended Operating Range:
- DVDD (Power Supply Voltage): 2.7V to 3.6V at Ta = -20°C to 85°C, DVSS = 0V
- Input Voltage Range (Certain pins): 0 to DVDD
- Input Voltage Range (OPINM1, OPINM3): 0 to VM
️· Electrical Characteristics (Input/Output):
- VIH (High-Level Input Voltage): 0.7 x DVDD
- VIL (Low-Level Input Voltage): 0.2 x DVDD
- VOH (High-Level Output Voltage): DVDD - 0.4V
- VOL (Low-Level Output Voltage): 0.4V
- Pull-Down Resistance (Certain pins): 40-200 kΩ
️· Reset Timing: DVDD and ZRESET (reset pin) have specific timing requirements to ensure proper device initialization.
- Time from DVDD rise to ZRESET rise: 1ms.
- Time from DVDD fall to ZRESET fall: 500 µs
- ZRESET Low period: 100 µs

3. Power Supply Considerations - VM (Secondary Power, Likely for Display)

️· Absolute Maximum Ratings:
- Supply Voltage (VM max): -0.3V to 7.0V
- Output Peak Current (OUT7A/B): 450mA
- Output Continuous Current (OUT7A/B): 300mA
- Storage & Operating Temperatures (same as DVDD)
️· Recommended Operating Range: VM: 2.7V to 5.5V
️· Electrical Characteristics: (Relates to driving display outputs)
- ON Resistance (P-channel and N-channel transistors within VM outputs)
- Diode Forward Voltage (related to VM outputs)
