MAX1558HETB+T

Maxim Integrated · Interface - Specialized · TDFN-10-EP(3x3)

MAX1558HETB+T from Maxim Integrated, in a TDFN-10-EP(3x3). Pinout and pin descriptions extracted from the manufacturer datasheet (extract_pins, cross-checked by a second model); symbol, footprint, and 3D from KiCad-official CAD.

Pinout

Pin Name Type Function
1 INA power_in Power input for OUTA; connect INA and INB together and bypass with a 0.1µF capacitor to ground (2.7V to 5.5V supply).
2 ONA input Control input for switch A (active-high on the MAX1558H, a logic high turns switch A on); can be driven higher than IN_ without damage.
3 ISET passive Current-limit adjust for both channels; connect a 26kΩ to 60kΩ resistor from ISET to ground to program the current limit.
4 ONB input Control input for switch B (active-high on the MAX1558H, a logic high turns switch B on); can be driven higher than IN_ without damage.
5 INB power_in Power input for OUTB; connect INB and INA together and bypass with a 0.1µF capacitor to ground.
6 OUTB power_out Power output for switch B; connect a 1µF capacitor from OUTB to ground, with additional bulk capacitance if the load requires.
7 FLTB output Open-drain fault indicator for switch B; goes low in thermal shutdown, UVLO or a sustained (>20ms) current-limit or short-circuit condition.
8 GND power_in Ground.
9 FLTA output Open-drain fault indicator for switch A; goes low in thermal shutdown, UVLO or a sustained (>20ms) current-limit or short-circuit condition.
10 OUTA power_out Power output for switch A; connect a 1µF capacitor from OUTA to ground, with additional bulk capacitance if the load requires.
11 PAD passive Exposed pad (from the footprint; not named in the datasheet pin table).
