USB Charger Detectors
General Description
Benefits and Features
● High Level of Integration
The MAX14576/MAX14636/MAX14637 are USB charger
detectors. The MAX14576/MAX14636/MAX14637 will
pass USB Battery Charger Specification Revision 1.2 (USB
BC 1.2) compliance tests. The MAX14636/MAX14637 can
also detect Apple chargers, and other nonstandard types.
These devices are capable of detecting multiple USB
battery charging methods, including standard downstream
ports (SDP), charging downstream ports (CDP), and dedi-
cated charger ports (DCP). The devices also feature USB
BC 1.2 defined dead-battery option support.
• Capability to Withstand -6V to +30V (Absolute
Maximum) on VBUS Line
• USB Battery Charger Detection
- Will Pass USB Battery Charger Specification
Rev 1.2 Compliance Tests
- USB DCP, SDP, and CDP Detection
- Proprietary Charger Detection Capability
(MAX14636/MAX14637)
• USB 2.0 Hi-Speed Switch with 3Ω (typ) On-Resistance
and 4.5pF (typ) On-Capacitance
• High ESD Protection on CDP and CDN
- ±15kV—HBM
- ±15kV—IEC 61000-4-2 Air-Gap Discharge
- ±8kV—IEC 61000-4-2 Contact Discharge
• ±15kV HBM ESD Protection VBUS When Bypassed
with 0.1µF or Greater Ceramic Capacitor
The MAX14576/MAX14636/MAX14637 feature analog
switches that are capable of passing USB Hi-Speed, full-
speed, and low-speed signals. The switches have low on-
resistance (3I, typ) and low on-capacitance (4.5pF, typ).
The CDN and CDP are high ESD protected up to Q15kV
Human Body Model (HBM), Q15kV IEC61000-4-2 Air Gap
Discharge, and Q 8kV IEC61000-4-2 Contact Discharge.
● Save Power in Portable Applications
The MAX14576/MAX14636/MAX14637 are available in
a 10-pin (1.6mm x 2.1mm) UTQFN package and operate
over the 0°C to +70°C extended temperature range.
• Low Supply Current (150µA, typ)
● Space Saving
• 10-Pin, 1.6mm x 2.1mm, UTQFN Package

Detailed Description
The MAX14576/MAX14636/MAX14637 detect battery
charging sources as defined in USB Battery Charging
Specification Rev 1.2 (USB BC 1.2). These devices
are capable of detecting multiple USB battery charging
methods including SDP, CDP, and DCP. The MAX14636/
MAX14637 are also capable of detecting Apple chargers,
and other nonstandard types (e.g., TomTom charger, and
PC PS2 adapter). The devices also feature USB BC1.2
defined dead battery option support.
timer starts, V
is set on CDP and the device is
DP_SRC
allowed to charge at a 100mA rate. During DB mode, if
GOOD_BAT goes high, then DB mode ends, V
DP_SRC
is removed and USB switches are closed. If GOOD_BAT
goes low again before the 45 minute timer expires, DB
mode is entered again. If GOOD_BAT is low when the
45 minute timer expires, DB mode ends and the device
is not allowed to charge until VBUS is removed and
reconnected. For GOOD_BAT sensitivity in DB mode,
the MAX14576/MAX14636 treat CDP as SDP and the
MAX14637 treats CDP as DCP.
USB Charger Detection
The charger detection starts when VBUS rises above
the threshold. After the type of charger is determined,
the MAX14576/MAX14636/MAX14637 set SW_OPEN,
CHG_AL_N, and CHG_DET according to the charger
type found (Table 1, Table 2, Table 3).
USB Switches
The switches between CDP/CDN and TDP/TDN are low
capacitance and low resistance, and capable of passing
Hi-Speed USB signals. The switches are normally open
when no valid VBUS is present. When valid VBUS is
applied, the switches act according to the charger found
(Table 1, Table 2, Table 3).

ESD Test Conditions
Applications Information
ESD performance depends on a variety of conditions.
Contact Maxim for a reliability report that documents test
setup, test methodology, and test results.
Hi-Speed USB
Hi-Speed USB requires careful PCB layout with 45Ω
single-ended/90Ω differential controlled-impedance
matched traces of equal lengths.
Human Body Model
Figure 4 shows the Human Body Model, and Figure 5
shows the current waveform it generates when discharged
into a low impedance. This model consists of a 100pF
capacitor charged to the ESD voltage of interest that is
then discharged into the device through a 1.5kΩ resistor.
Extended ESD Protection
ESD protection structures are incorporated on all pins
to protect against electrostatic discharges up to ±2kV
(Human Body Model) encountered during handling and
assembly. CDN and CDP are further protected against
ESD up to ±15kV (HBM), ±15kV (Air-Gap Discharge
method described in IEC 61000-4-2) and ±8kV (Contact
Discharge Method described in IEC 61000-4-2) without
damage. The VBUS input withstands up to ±15kV (HBM) if
bypassed with a 0.1µF ceramic capacitor close to the pin.
IEC 61000-4-2
The IEC 61000-4-2 standard covers ESD testing and
performance of finished equipment. However, it does not
specifically refer to integrated circuits. The major difference
between tests done using the Human Body Model and
IEC 61000-4-2 is higher peak current in IEC 61000-4-2
because series resistance is lower in the model. Hence,
the ESD withstand voltage measured to IEC 61000-4-2
is generally lower than that measured using the Human
Body Model. Figure 6 shows the IEC 61000-4-2 model,
and Figure 7 shows the current waveform for the IEC
61000-4-2 ESD Contact Discharge test.
The ESD structures withstand high ESD both in normal
operation and when the device is powered down. After
an ESD event, the MAX14576/MAX14636/MAX14637
continue to function without latchup.
