NAME
FUNCTION
1
IN1
Switch Input Channel 1. Connect IN1 to a switch connected to GND. IN1 can be programmed as a direct
input with a level-shifted output on DO1 (see the Mechanical Switch Inputs (IN0–IN7) section).
2
IN2
Switch Input Channel 2. Connect IN2 to a switch connected to GND.
3
IN3
Switch Input Channel 3. Connect IN3 to a switch connected to GND.
4
IN4
Switch Input Channel 4. Connect IN4 to a switch connected to GND or BAT.
5
IN5
Switch Input Channel 5. Connect IN5 to a switch connected to GND or BAT.
6
IN6
Switch Input Channel 6. Connect IN6 to a switch connected to GND or BAT.
7
IN7
Switch Input Channel 7. Connect IN7 to a switch connected to GND or BAT.
8, 20, 27
N.C.
No Connection. Not internally connected.
9
HYST
Hysteresis Input. Connect HYST to GND with a 0 to 900k
Ω resistor to set the input voltage hysteresis on
IN0–IN7.
10
WET
Wetting Current Input. Connect a 30k
Ω to 330kΩ resistor from WET to GND to set the wetting current on
IN0–IN7.
11
TDEB
Switch Debounce Time Input. Connect a 500pF to 10nF capacitor from TDEB to GND to set the switch
debounce time.
12, 24
GND
Ground
13
OT
Overtemperature Warning Output.
OT is an open-drain output that asserts low when the thermal warning
threshold is exceeded.
14
INT
Interrupt Output.
INT is an open-drain output that asserts low when one or more of the IN0–IN7 inputs
change state and is enabled for interrupts.
15
CS
SPI Chip-Select Input. Drive
CS low to enable clocking of data into and out of the MAX13036. SPI data is
latched into the MAX13036 on the rising edge of
CS.
16
SDO
SPI Serial Data Output. SPI data is output on SDO on the rising edges of CLK while
CS is held low. SDO
is tri-stated when
CS is high.
17
SDI
SPI Serial Data Input. SPI data is latched into the internal shift register on the falling edges of CLK while
CS is held low. SDI has an internal 100k
Ω pulldown resistor.
18
CLK
SPI Serial Clock Input
19
VL
Logic Power-Supply Input. Connect VL to a positive 2.7V to 5.5V power supply. Bypass VL to ground with
a 0.1F capacitor placed as close as possible to VL.
21
DO1
Data Output Channel 1. DO1 is the level-shifted output of IN1 when WEND = 0 (normal mode only).
22
DO0
Data Output Channel 0. DO0 is the level-shifted output of IN0 when WEND = 0 (normal mode only).
23
SD
Shutdown Input. Drive
SD low to place the MAX13036 into shutdown mode. Drive SD high for normal
operation.
SD is compatible with voltages up to +45V.
25
BATREF
Battery Reference Input. Switch thresholds are set to 50% of the voltage applied to BATREF. Connect
BATREF to the system’s battery supply voltage.
26
BAT
Battery Supply Input. Connect BAT to a positive 6V to 26V battery supply voltage. Bypass BAT to ground
with a 0.1F ceramic capacitor placed as close as possible to BAT. In addition, bypass BAT with a 10F
or greater capacitor.
28
IN0
Switch Input Channel 0. Connect IN0 to a switch connected to GND. IN0 can be programmed as a direct
input with a level-shifted output on DO0 (see Mechanical Switch Inputs (IN0–IN7) section).
EP
Exposed Paddle. Connect EP to GND.
