G2581

G2581
Global Mixed-mode Technology
9-CH Level Shifters
Features
General Description
„ Input Supply Range: 2.6V~5.5V
The G2581 is a 9-channel level shifter suitable for
TFT-LCD row drivers. This device will level shift a digital input signal to an output voltage nearly equal to its
output supply voltage.
„ Protection Function
Š Input Under Voltage Lockout (UVLO)
Š Thermal Overload Protection (150°C)
„ 9-Channel Level Shifter
The G2581 has 3 supplies: VIN, VGH and VGL1. VIN
is low voltage supply with a voltage range from 2.6V to
5.5V. VGH is positive high voltage supply with a voltage range from 7V to 40V. VGL1 is negative high
voltage supply with a voltage range from 0V to -30V.
CKO_1~CKO_6 are level shifter outputs with gate
shading function. STO and LCO_1~LCO_2 are level
shifter outputs without gate shading function.
Š +40V Highest Voltage Level
Š -30V Lowest Voltage Level
Š Maximum 700ns Rising/Falling Time
Š 500mA Peak Current
Š 20mA Continuous Current
Š Gate Shading Function.
„ 32-pin, QFN (5mmx5mm) Package
„ RoHS Compliant
The G2581 features extensive protection functions
that include UVLO, OTP. This device operates over
the temperature range from -40°C to +85°C.
Applications
