36V, 1A Octal Integrated Serial-Controlled

Solenoid and Motor Driver

General Description

Benefits and Features

The MAX22200 is an octal 36V serial-controlled solenoid

driver. Each channel features a low impedance (200mΩ

typ) push-pull output stage with sink-and-source driving

● Eight Half-Bridges Up To +36V

● High Performances:

• Low On-Resistance: R

: 200 mΩ typical (T =

DS(on)

capability and up to 1A

driving current. A serial inter-

RMS

face (SPI) that also supports daisy-chain configurations is

• Continuous Output Current Up To 1A

per Half-

RMS

provided to individually control each channel.

Bridge (T = +25°C)

• Current-Drive Regulation (CDR)

• Voltage-Drive Regulation (VDR)

• Integrated Lossless Current Sensing (ICS)

The device half-bridges can be configured as low-side

drivers or as high-side drivers. Moreover, pairs of half-

bridges can be paralleled to double the driving current or

can be configured as full-bridges to drive up to four latched

valves (bi-stable valves) or four brushed DC motors.

● High Flexibility:

• Independent Programmable HIT and HOLD

Currents for Each Channel (I , I

)

HIT HOLD

Two control methods are supported: voltage drive regu-

lation (VDR) and current drive regulation (CDR). In VDR,

the device outputs a PWM voltage in which the duty cycle

is programmed using SPI. For a given supply voltage and

solenoid resistor, the output current is proportional to the

programmed duty cycle. In CDR, an internal integrated

lossless current sensing (ICS) circuit senses the output

current and compares it with an internal programmable

reference current.

ually configured for each channel.

The MAX22200 features a full set of protections and di-

agnostic functions. This includes overcurrent protection

(OCP), thermal shutdown (TSD), undervoltage Lockout

(UVLO), open-load detection (OL), and detection of

plunger movement (DPM). A fault indication pin (FAULT)

signals fault events and diagnostic information is stored in

the FAULT register.

● Integration:

• 32 TQFN 5mm x 5mm Package

Ordering Information appears at end of datasheet.

Due to the flexibility of use, the serial interface control,

the high efficiency, and the small package, the MAX22200

is particularly well-suited for solenoid driver applications

(valve control, relays control etc.) in which low power con-

sumption and high level of integration are required.

The MAX22200 is available in a compact 5mm x 5mm,

32-pin TQFN package and operates over the temperature

-40ºC to +85ºC range.

Applications

● Relays Driver

● Solenoid, Valves, Electromagnetic Drivers

● Generic Low-Side and High-Side Switch Applications

● Latched (Bi-Stable) Solenoid Valve Drivers

● Brushed DC Motor Driver
