MAX1600EAI (IC212)
Function Pin No. Pin Name
MAX1600EAI Pin Description
1 GND Ground
2 A1VPP Channel A VPP Control Input.
3 A0VPP Channel A VPP Control Input.
4 12INA +12V Supply Voltage Input, internally connects to channel A VPP switch. Tie to VPPA if not used.
5 VPPA Channel A VPP Output.
6, 8, 10 VX VX Supply Voltage Inputs. VX pins must be connected to one another. Input range is +3V to +5.5V. VX is
normally connected to 5V.
7, 22, 24 VCCA Channel A VCC Outputs.
9, 18, 20 VCCB Channel B VCC Outputs.
11 VPPB Channel B VPP Output.
12 12INB +12V Supply Voltage Input, internally connects to channel B VPP switch. Tie to VPPB if not used.
13 B0VPP Channel B VPP Control Input.
14 B1VPP Channel B VPP Control Input.
15 B0VCC Channel B VCC Control Input.
16 B1VCC Channel B VCC Control Input.
17 FAULT Fault-Detection Output. FAULT goes low during current limit, undervlotage lockout, or thermal limit. FAULT is
an open-drain output that requires an external pull-up resistor.
19, 21, 23 VY VY Supply Voltage Inputs. VY pins must be connected to one another. Input range is +3V to +5.5V. VY is
normally connected to 3.3V.
25 CODE Three-Level Code-Select Input.
Low=Standard "Intel" code
High="Cirrus" code
Mid-supply="Databook" code
26 A1VCC Channel A VCC Control Input.
27 A0VCC Channel A VCC Control Input.
28 VL Logic Supply-Voltage Input. Connect to the +3.3V or +5V host system supply.
